Earlier this year, many tennis fans were talking about the Australian Open finals. American tennis stars and sisters Serena and Venus Williams played each other in a so-called Grand Slam final for the first time since 2009. Serena beat her older sister in two sets to win the Australian Open. Little did we know, Williams was in her eighth week of pregnancy at the time. This week, she posted a photo of herself wearing a yellow bathing suit on social media. On the photo she wrote “20 weeks.” Fans immediately started talking and debating. Was Serena pregnant? A spokeswoman later confirmed Williams’ pregnancy. She also confirmed that she would not play in tennis competitions for the rest of the year. The spokeswoman said Williams expects to return to tennis in 2018, however. The baby is due sometime in the fall. Williams is set to marry internet businessman Alexis Ohanian.
