Elon Musk's mother, Maye Musk, has been revealed as one of the faces of Sports Illustrated Swimsuit 2022.

At 74, the longtime model, author, and dietician-nutritionist has made history as the magazine's oldest cover star.

She had the opportunity to grace the cover of the swimsuit magazine with model Yumi Nu, singer Ciara, and businesswoman Kim Kardashian.

The American sports magazine posted Musk's cover on Instagram with a caption describing her as a "legend in the modeling industry for more than five decades."

It went on to say that the model "embodies the idea that aging shouldn’t hold you back from pursuing your dreams."

Speaking to PEOPLE, the dietician opened up about her excitement and the significance of being on the cover.

"My first reaction was, I could never dream up something like that because why would anyone have a 74-year-old on their cover, especially in a swimsuit," she joked.

"I do think it's going to make women feel more comfortable in their seventies when they swim, as well as women in their twenties and thirties."

"When women go to the beach, we're kind of shy about our bodies, but men will walk around, looking terrible, and they don't care," she continued. "I think we have to not care that much!"

Musk wore a purple swimsuit - seen in images inside the magazine - and a colorful Maygel Coronel one-piece on the cover. She said, initially, she was unnerved by going to Belize to shoot with photographer Yu Tsai, however, it ended up being a "lovely atmosphere."

"Everybody was polite, kind, considerate, caring, so I felt very comfortable in my swimsuit," she said, adding that "once you've done your first shot, you're fine with all the others because they give you so much confidence about looking good in a swimsuit."

Musk reflected on her body image and aging in her 2019 memoir, A Woman Makes A Plan: Advice for a Lifetime of Adventure, Beauty, and Success.

She wrote: "I went through different stages of my life where I was rejected, insulted, disappointed and it just takes away your confidence.

"Then you just have to get over it. So here, I'm 74, I'm the happiest I've ever been, and I don't care, and nobody's insulting me because — you don't want to insult a grandmother. The point is, people are really good to me at this stage, but why should it take so long?"

Also as part of the 2022 Sports Illustrated Swimsuit issue, Musk's 47-year-old daughter, Tosca, wrote an essay titled The Unstoppable Force, as a homage to her mom.

"My whole life, I've seen my mom do everything. As a result, I think I'll always expect her to be able to do everything," Tosca shared. "Sometimes I wonder whether it's time I start limiting those expectations, as she gets older. But then I look at her again, still unstoppable, and I think, not yet."

Tosca spotlighted a few of her mom's achievements, writing:  "My mom is 74 now. In her years on this planet she's earned two master's degrees in nutrition science, won awards in the dietetics field, has been in countless fashion shows and editorials, and she's even appeared in a Beyoncé video. She is an uncontainable force, and she's the most fearless woman I've ever known."

Life sure is hard for those who have won the genetic lottery. You know, with their killer good looks and enviable physique, they face a lot of problems on a daily basis. I mean, who can deal with having their friends, colleagues and family members constantly reminding them of how beautiful they are?

Now, while this is certainly the life that one age-defying grandmother leads, Gina Stewart is also committed to utilising her looks for a good cause. The model, who has four children, has been knocking out hundreds of women half her age for the title of Miss Maxim 2018. And with her glowing complexion and generally youthful appearance, people were nonplussed to discover just how old she really is...

The Aussie is one of the finalists in the running for this year's Miss Maxim competition. And while she has four children (two sons and two daughters, respectively aged 4, 23, 25 and 27) as well as a 10-month-year-old granddaughter, she doesn't look her age at all. Yes, Gina - who has over 42,000 followers on Instagram - is 47-years-old.

The model, who became a grandmother last year, has now revealed the "secrets" to her ageless complexion. "The only cosmetic procedure I had was my breasts 10 years ago. I don't use Botox or fillers as I believe in ageing gracefully," she told Daily Mail Australia.

"But seriously, there's no secret. I think everyone is beautiful. I'm not doing this for attention as I hate it. I'm just trying to make a difference to inspire women not to rip each other apart."

"Life is too short for judgement. Embrace your age and your curves, it never killed anyone," she added.

Gina is competing for the title of Miss Maxim 2018 for a great reason. She revealed that if she wins, she will donate the $10,000 prize money to a friend who recently suffered a stroke. "I'm only hoping to win to help my best friend of 30 years as she's had a stroke," she asserted. "If I win Maxim, I would be donating to her to help with her recovery. I'm just hoping to raise awareness for stroke victims."

When quizzed on where she draws her inspiration from, Gina revealed that much of it comes from the friend in question. "People who still have the strength to keep going and be positive even after going through hard times. People that never give up really I find the most inspirational." She added that she also has great respect for "people who do what they say they are going to do."

Looks certainly don't mean everything to the single mother. On her Maxim profile, Gina listed that her "best features" include her "sense of humour", how much she "cares about people, friends and family", as well as her laugh.

She also revealed that she's quite the foodie. When asked what she'd do if she could rule the world for a day, she replied that she would "Make it so that Chocolate, Peanut Butter and Nutella would all have zero calories" - I mean, we're with you there girl.

We certainly wish Gina all the best for the competition, but either way, it's evident that she's doing pretty great already.

In other news, people are falling desperately in love with this blogger's photo of her rolls.

When we look at celebs like Jennifer Lopez or George Clooney, we only lament the fact that they only seem to get better-looking with age for a second. Because we know that they're super rich and famous, which means they have the means to pay for nutritionists and skin-care advisors who hook them up with magical elixirs made from exotic ingredients we've never even heard of. Not to mention that their careers consist of huge audiences looking at them all the time, so self-grooming and keeping up appearances is kind of a job requirement.

We all think, "eh, I don't have the time and money to do all that", so will excuse ourselves when the inevitable grey hairs start to show up and the dad bods begin to emerge (and so what, it's only natural!?). However, the occasional person comes along who, despite being a mere mortal like the rest of us, has somehow managed to avoid the effects of ageing.

I mean, it's good for us all to wear sunscreen, drink plenty of water and exercise regularly for our general well-being - as well as to fend off the signs of ageing - but it's never going to obscure the fact that we are normal human beings who do indeed grow older as the years press on. But for some people, it actually does...

Like this mother, who recently captivated the attention of the internet due to the fact that she looks the same age as her daughter. Twitter user Krissy Nicole uploaded two pictures of her standing with her mother in a post dedicated to her, writing in the caption: "Thank you for literally everything you do for me mother. I love you". It's pretty cute, and they do look very glam standing together.

Only... people found it very difficult indeed to figure out who was the mother, and who was the daughter. You've got to admit, they both look like they could be the same age - like sisters or best friends!

The post was swarmed with comments from people who said they could easily be siblings...

To which Krissy responded that her mum is her best friend.

Others thought the two of them looked like Ashley Benson and Shay Mitchell, the young actresses from Pretty Little Liars.

Alright, I'll put you out of your misery, in case you haven't figured it out yet: Krissy is the one with dark hair, and her mother is the blonde one. All it takes is a glance at Krissy's Twitter avatar to figure it out.

Who knows what her mother's secret is - but, even though she's gorgeous on the outside, it seems she's beautiful on the inside too, based on Krissy's original post.

1. This result is stunning 

2. Wow

3. Can you believe it's the same person? 

4. Beautiful 

5. We love the lipstick choice, here

6. She looks ten years younger!

7. So youthful 

8. This lady is ready to hit the town 

Some people seem to just have the gift of never aging a day, don't they?

While the rest of us wrestle with dubious face creams promising improbable results, drink copious amounts of water every day, and moisturize like we're preparing to break the land speed record on a slip and slide, others seem to just stroll through life apparently unblemished by the aging effects of Father Time.

Of course, aging is something that should be celebrated, meaning as it does that we're another year older and wiser, with a lifetime of experiences to look back on.

Seriously, Hayek looks the same as she did when she starred in From Dusk Till Dawn:

[[jwplayerwidget||https://content.jwplatform.com/videos/vqnnGwUe-sKUnNGKf.mp4||vqnnGwUe]]

Salma Hayek is certainly someone whose name crops up often when we talk about celebrities who never seem to have aged a day. Her Instagram page is constantly flooded with fans expressing their amazement over her youthful looks, and a recent post from the actress in celebration of her 54th birthday was no exception.

"I am very grateful and proud for every single one of my 54 years. Thank you for all the birthday wishes, especially to my fans who made a special account for my birthday. What a gift!" the actress wrote on Instagram, alongside a picture of herself happily posing in a golden swimsuit.

And her fans were delighted with the birthday post. "Are you ageing or anti-ageing !!! Beautiful" wrote one commenter, while another added, "Happy birthday. You definitely don't look 54 years young you look 28".

A third commenter wrote, "How is she 54? Godess [sic]".

Another well-wisher added, "Happy Birthday Gorgeous more like 24".

In a 2016 interview with Harper's Bazaar. Hayek discussed getting older, telling the publication:

"Well I am entering my fifties so your body confidence isn’t that good. I think it depends on the day, for everybody, there’s some days you say, ‘This is it,’ and you love it. Then there are days when you go, ‘This can not be it! Is this really it?’ So I think it’s up and down all the time!"

And the Like A Boss star previously revealed some of her best beauty tips in an interview with The New York Times, revealing in 2017:

"I never cleanse my skin in the morning. My grandmother taught me that at night your skin replenishes all the things you lost during the day. Also, if I cleanse very well at night, why would it be dirty when I wake up? It’s for companies to have you use more products.

"At night I take off my makeup with coconut oil. Then I use rose water to take off the residuals. You can use a hot towel with the rose water — you put a wet towel in the microwave — to do a little steam. I’ll use the chamomile cleanser from Nuance. Then I splash with cold water."
