Serena Williams had a very special guest cheering her on at the Fed Cup on Saturday: 5-month-old daughter Alexis Olympia
The 36-year-old tennis champ shared a video from the tennis court to her Instagram Stories, showing husband Alexis Ohanian holding their adorable child from their courtside seats.
Baby Olympia appeared happy at the match, wearing a pink and white headband decorated with an oversized pink flower.
It was a special occasion for Williams, as she was making her competitive return to tennis at the Fed Cup after giving birth to Olympia in September.

In January, Williams was supposed to return to the Australian Open —which she won last year when she was about eight weeks pregnant— but eventually withdrew from the competition in September after playing (and losing) her first post-maternity match.
“After performing in my first match after giving birth I realized that although I am super close I’m not where I personally want to be,” Williams wrote on Snapchat, referencing her Dec. 30 defeat. “My coach and team always said ‘Only go to tournaments when you are prepared to go all the way.’ With that being said I am disappointed to say I’ve decided not to compete in The Australian Open this year.”
“However, the memory of last year’s Open is one that I will carry with me and Olympia and I look forward to coming back again. I appreciate the support and understanding of my fans and everyone at the Australian Open,” she concluded.
Williams’ friend Caroline Wozniacki went on to win won the Australian Open and became the new world No. 1.
The Fed Cup will have Williams playing in the first-round matches against the Netherlands in Asheville, North Carolina, on Saturday and Sunday.
And helping her defend the country’s Fed Cup championship is her sister Venus Williams. It will be the first time in two years that either Williams sister has been on the team.
