Serena Williams new biggest fan is also her littlest one - her daughter, Alexis Olympia.

The tennis star’s husband, Alexis Ohanian, was front and center with their 5-month-old little girl cheering mom on. It was clear she is Williams' biggest fan.

Over the weekend, Williams had her big return to professional tennis since giving birth, and it was truly a family affair. Not only were her hubby and baby at the 2018 Fed Cup in Asheville, North Carolina, but she also played doubles with her sister, Venus.

Serena and Venus unfortunately lost their match to Lesley Kerkhove and Demi Schuurs from the Netherlands. However, the new mom is not worried at all about her game. In fact, having her little girl there to root for her gave her more confidence.

“I honestly feel better than I thought I was going to feel. I feel like I’m on the right track for me,” she shared after the match.

The tennis pro was supposed to return to the game at the Australian Open in January 2018. But do to complications from her C-section with Alexis, she had to back out at the last minute.

Even though she feels confident about her tennis career, like all mothers, Serena gets down on herself and questions what she is doing.

“Sometimes I get really down and feel like, ‘Man, I can’t do this. No one talks about the low moments, the pressure you feel, the incredible letdown every time you hear the baby cry. I’ve broken down I don’t know how many times. Or I’ll get angry about the crying, then sad about being angry, and then guilty, like, ‘Why do I feel so sad when I have a beautiful baby?’ The emotions are insane,” Williams said in a recent interview with Vogue.

Along with playing tennis, Williams has also been tapped to be the voice of the new Ford Lincoln navigating system. Yes, she is going to be one busy woman as the company will feature her in a new ad campaign, as well.

Being a new mother and a professional tennis goddess is not always going to be a breeze. But if anyone can do it, Serena Williams can, especially with her daughter Alexis cheering her on.
