World number two, Serena Williams, has taken to social media to announce she is pregnant.
The 35-year-old posted a picture of herself on Snapchat posing in a mirror with the message: “20 weeks”.
This means that Serena, who won a record 23rd Grand Slam in Australia this January, will miss most of the remaining tennis season.
These include three Grand Slams: the French Open, Wimbledon and US Open.
The tennis star is engaged to Reddit founder, Alexis Ohanian.
