Over the past week or so, the good people over on Twitter have been sharing their glow-ups from 2012 to the current day, and some of the results have really shocked people. After all, six years might not seem like a very long period, but, if a person happens to experience the joy of puberty during that time, they could go from looking like a skinny little kid to a fully-fledged grownup.

But, when you see that person on a fairly frequent basis - either up close and personal or on TV - it's difficult to really appreciate the difference between their former selves and how they are now. Just take a look at these 10 former child stars and you'll understand what I mean...

1. Emma Watson must've used some sort of magic for this transformation

2. Georgie Henley's trip to Narnia has clearly kept her looking youthful

3. Jonathan Lipnicki ain't so Stuart Little anymore

4. Zac Efron went from a goofy tween to a serious heartthrob

5. Alexa PenaVega might've been a Spy Kid once, but now she's married with a child

6. Josh Peck might not have been the hotter brother before, but he definitely is now

7. Alfred Enoch started life in Hogwarts, now he's trying to get away with murder

8. Tania Raymonde has the most stunning glow-up from the Malcolm in the Middle cast

9. Abigail Breslin might have been Little Miss Sunshine once, but not anymore

10. Matthew Lewis took on the challenge of puberty and won

While it's amazing to see all the stars of our childhoods all grown up and living their lives as adults, it's also sort of scary to see how much has changed in such a short period of time. It only seems like yesterday that I was settling down to watch Spy Kids or Harry Potter with my family - and now those actors are probably sharing their work with their own kids.

The never-before-seen personal diaries of the late actor Alan Rickman reveal his true feelings about working with child co-stars in the Harry Potter franchise.

Published by The Guardian, the actor - who died from prostate cancer in 2016 at the age of 69 - had allegedly kept a pocket diary since the 1970s, before starting to write more detailed entries in the 1990s.

Included in those entries are 10 years of notes written by Rickman about his time as Professor Snape in the Harry Potter movies.

His first entry in relation to the hit franchise was from August 23, 2000, in which the then-54-year-old wrote: "6:30 PM Pile into the car and drive to Siena to get to Il Campo before dark. To the Patio Bar where, around 8:00 PM, I called LA and said OK to HP [Harry Potter]."

On September 10, Rickman writes about reading the first Harry Potter novel, written by J. K. Rowling: "Perfect day. Still, sunny. To the pool. Finish [reading] HP 1, start 2."

A week and a half later the Love Actually star detailed his experience during a costume fitting for Harry Potter: "HARRY P TAKES OFF. 10:30 AM Car to costume fitting/discussion. Measurements from hell after a month in Italy. Waltz around each other – higher collar? Blue fabric? Thinner arms? And off to Leavesden Studios. Chris Columbus [director], David Heyman [producer], Makeup dept waiting. Wig? Nose?"

Then, in December 2002, Rickman detailed that he wanted to leave the wizarding movie series after the first two flicks, penning an entry that read: "Talking to [agent] Paul Lyon-Maris about HP exit, which he thinks will happen. But here we are in the project-collision area again. Reiterating no more HP. They don't want to hear it."

Yet, in January 2006, the London native wrote about his desire to continue working on the franchise - after having already filmed four movies: "Finally, yes to HP 5. The sensation is neither up nor down. The argument that wins is the one that says: 'See it through. It's your story.'"

Rickman's entries further included many of his personal opinions on politics, life, and his famous colleagues - including his Harry Potter co-stars, Daniel Radcliffe and Emma Watson.

Two entries, written in 2003, directly address Radcliffe and Watson - who played Harry Potter and Hermione Granger.

"I still don't think he's really an actor but he will undoubtedly direct/produce," Rickman said about Radcliffe, while adding two months later: "These kids need directing. They don't know their lines and Emma [Watson]'s diction is this side of Albania at times."

Rickman also cheekily dissed numerous other celebrities, included infamous bad boy, Liam Gallagher. "Liam Gallagher is a great rock singer but an absolute tosser as a person," the Die Hard star wrote.

The entries make up part of an upcoming book about Rickman's life through his diary entries. Madly, Deeply: The Alan Rickman Diaries, will be out on October 18.

Robbie Coltrane - the beloved star who played the beloved Hagrid in the Harry Potter movies - passed away yesterday (October 14) at the age of 72.

The Scottish actor and comedian played rugged gamekeeper Rubeus Hagrid in all eight installments of the magical movie franchise, starring alongside then-child actors Daniel Radcliffe, Emma Watson, and Ruper Grint.

As tributes from Coltrane's Potter co-stars pour in, many people are remembering the fond way that Coltrane himself described his relationship with them.

During an interview on HBO's reunion special 'Harry Potter 20th Anniversary: Return to Hogwarts', the actor reflected on what it was like watching the young cast grow up.

"You've got to remember, when they first started they were about eight. I think the oldest of them was 11," Coltrane said in the special, which aired on New Year's Day 2022.

"Now they’re big grown-ups with their own lives. Grint's had a baby – Grint’s now a father! It’s just astonishing, the change," he continued, adding: "Watching them growing up was kind of like watching your own grow up, you know? Because you were protecting them."

Coltrane shares two children with his ex-wife Rhona Gemmell: Spencer, born in 1992, and Alice, born in 1998.

Coltrane went on to praise his young co-stars, saying: "I was always astonished at how fearless they were. I remember walking into The Great Hall, and I've been doing this for 30 years, and I thought, 'Dear Lord! Woah, better get this one right.'"

"I do have enormous happy memories of this actually," he added.

Following news of Coltrane's death, Radcliffe penned his own emotional tribute to the star.

"Robbie was one of the funniest people I've met and used to keep us laughing constantly as kids on the set. I’ve especially fond memories of him keeping our spirits up on 'Prisoner of Azkaban,' when we were all hiding from the torrential rain for hours in Hagrid’s hut and he was telling stories and cracking jokes to keep morale up," he said in a statement to Variety.

"I feel incredibly lucky that I got to meet and work with him and very sad that he’s passed," Radcliffe continued, adding: "He was an incredible actor and a lovely man."

As well as starring in the Potter movies, Coltrane was also known for his villainous turn in the Bond flicks GoldenEye (1995) and The World Is Not Enough (1999). In 2006 he was appointed an OBE for his services to drama, and in 2011, he was awarded a Scottish BAFTA.

Our thoughts continue to go out to Coltrane's family, friends, and fans at this time.

Millie Bobby Brown has revealed that some of her biggest fans are having trouble "accepting" that she's all grown up.

The actor first gained international fame back in 2016 after her role as the mysterious and powerful Eleven in the Netflix series Stranger Things. Brown was just 12 years old when she first appeared on the critically acclaimed sci-fi show, meaning we have watched the young star grow up into a multi-talented teenager.

It has always been a case that Brown is talented beyond her years, and Time magazine even named her one of its 100 Most Influential People of 2018 - making her the youngest person ever to be named on the list.

But just like a parent watching their child pack up and leave for college, the now-17-year-old has admitted that some of her fans find it difficult to accept that she's all grown up.

Speaking to MTV, the Enola Holmes star revealed that people have becoming "invested" in her journey as an actress after getting to know her from such a young age.

"Being a young girl, people watch you grow up, right? And they've almost become invested in your growth and your journey, but they aren't ready to accept the fact that you're growing up," she said.

Brown then spoke about the backlash she has received due to some of her outfit choices for red-carpet events.

Perhaps most-famously at last year's Screen Actors Guild Awards in Los Angeles, a then-15-year-old Brown received a lot of comments for her outfit choice - pictured below:

In response, one Twitter user wrote: "Millie Bobby Brown is 15 years old. Everyone who is responsible for this look needs to get fired".

Another added: "She looks like she could be Natalie Portman or Celine Dion. I don't see a 15 year old here. She looks like she's an adult cast member crashing the teen photo."

Speaking to MTV, Brown - who turned 17 in February - said:  "[The fans are] not accepting it."

Laughing, she then added: "I've completely accepted it. You know, I'm ready.

"And it's kind of like, I have 50 million people like my parents and they're like, 'Noo!' And my parents are like, 'Yay! Thank God, you're 17!'"

Brown then added that she wants to "evolve", and doesn't want the industry to hold her back from certain roles just because of her age.

In recent years, a good number of us have associated Ryan Reynolds primarily with Deadpool.

Of course, the 44-year-old actor has worked on some other fantastic projects in the past, including... Sesame Street apparently.

Back in 2010, he played the letter A on the popular children's show. Sounds pretty wholesome, right?

Well, leave it to the infamous joker that is Ryan Reynolds to turn it into something a little more R-rated.

It all started when a fan of his tweeted: "Watching a little [Sesame Street] with the kiddo, and it's an episode with [Ryan Reynolds] and the gang doing an A-Team gag. It's a delight, for both me and the kiddo."

The tweet included two pictures of the actor dressed in his letter A costume. The costume came with a hole at the top for Ryan to fit his head through.

Responding to the tweet, the funny actor quipped: "I remember how challenging it was to sing because the A-hole was so tight. But I pushed through because kids all over the country were counting on me."

Needless to say, Ryan's R-rated tweet went viral, with over 18,000 retweets and more than 200,000 likes at the time of writing.

People had plenty to say in response to his clever play on words.

One impressed fan commented: "The speed at which you veer back and forth between filthy and wholesome is delightful."

Another shared: "I may just make this my screensaver."

A third said: "I'll take 'Things you can't say on Sesame Street' for $1000."

A different fan joked: "You... You pushed through the A hole? Ryan put this tweet back in the oven it’s not done yet."

And the responses to Ryan's epic tweet just kept pouring in, with yet another person tweeting: "families all over watched you poke ur head through that tight a-hole."

A different fan suggested: "Surely they could’ve loosened it a bit for you."

This Twitter user shared: "I hate singing with a tight a-hole... you’re a hero and an inspiration to us all Mr. Reynolds."
