Congrats are in order for Serena Williams. The tennis champion has just announced that she's pregnant, sharing the news with an adorable post on Snapchat. She's 20 weeks along.

The 35-year-old super star athlete announced that she's engaged to Reddit co-founder Alexis Ohanian back in December. In January, Serena beat her older sister, Venus, to win her 23rd Grand Slam singles title at the Australian Open.  The win pushed Serena to the No. 1 ranking in the world and broke fellow tennis icon Steffi Graf’s record of winning the most major titles in the Open era. It also established her as the oldest woman ever to win a major at age 35.

Congratulations to Serena and Alexis... take a look at the Snapchat post below.
