Serena Williams is pregnant. She posted a picture on Snapchat of her growing belly, saying she's 20 weeks along. This is the first child for Serena and her fiancé Alexis Ohanian. They're also planning their wedding, but there's no date yet.
On January 28th, Serena won the Australian Open. She didn't drop a single set, and she beat her sister Venus in the finals.
It was her 23rd major title, and if she's 20 weeks now, then she was almost two months pregnant when she won it.
Serena turns 36 in September, but this isn't the end of her career. She'll miss the rest of the season, but her rep says she'll be back on the court in 2018.
