Serena Williams has given birth to a baby girl

Serena Williams has rocked the world in more ways than one this year. After the announcement of her pregnancy, she still competed in the Australian Open in January, all while newly pregnant. Not only that, but she won the title too. Then of course was her nude photoshoot for Vanity Fair, which brought its own share of praise and criticism from the media and fans of the athlete.

Now the most significant news of her year has arrived, as the 23-time Grand Slam champion came out as the victor once again. She has given birth to a baby girl, and both the daughter and the undoubtedly ecstatic mother are reportedly in great health.

She was admitted to the St. Mary's Medical Center in West Palm Beach, Florida, on Wednesday. The first news we got came from her coach Patrick Mouratoglou, who tweeted: "I am so happy for you and I feel your emotion. Recover well & enjoy without limitation." But he still has work on the mind, as he added: "I wish you a speedy recovery... we have a lot of work ahead of us".

This news was later confirmed as various tweets were put out by the U.S. Open's official Twitter page, before Serena's sister Venus confirmed it. Speaking just before her match at the U.S. Open, Venus said: "Obviously I'm super excited, words can't describe it".

The 35-year-old tennis champion hasn't made any official statement yet, and neither has her partner Alexis Hoanian, one of the co-founders of Reddit. But as you can tell from her comments earlier in the year, she has no intentions of taking too long a break from the sport following the pregnancy. Last month she said she was planning to return to the sport for the Australian Open in January 2018, hoping to defend her title after her astounding win earlier this year.

Speaking to Vogue, she said: "It's the most outrageous plan. I just want to put that out there. That's, like, three months after I give birth." Another reveal from this interview was that Serena believed it would be a baby girl from the start, a prediction that was proven to be true this week:

"Alexis thinks we’re having a boy, but I have a strong suspicion that it’s a girl. Two weeks after we found out, I played the Australian Open. I told Alexis it has to be a girl because there I was playing in 100-degree weather, and that baby never gave me any trouble. Ride or die. Women are tough that way."

Many people, both from the sport and outside of it, have commented on the news. At a news conference Garbine Muguruza joked: "a baby girl? Well, I hope she doesn't play tennis". Across social media, other celebrities have wished Serena well on her journey into motherhood, from Nadal to Beyoncé.

And other fans have chimed in to remark on the birth:

We wish both Serena, Alexis, and their new baby girl the best of luck, and hope to be seeing those baby pics as soon as possible. I've got a good feeling she's going to have her own career in the world of sport someday.
