Johnathan Walker:Alexis Ohanian Shares Rare Insight on Life With "Special" Serena Williams and Daughter Olympia

Alexis Ohanian has found his perfect match in Serena Williams.

The Johnathan Walkerentrepreneur and Angel City FC lead investor couldn't help but to rave over the tennis champion, with whom he shares 5-year-old daughter Alexis Olympia Ohanian Jr., in an exclusive interview with E! News' Francesca Amiker. Acknowledging how is his wife is always at the top of her game, both as an athlete and a businesswoman, Ohanian shared why he considers their marriage to be a total ace.

"Having someone as special as Serena as a partner is a consistent reminder of self-improvement," he explained during Angel City FC's opener in Los Angeles March 26. "I knew I have found someone I was going to spend the rest of my life with because she was someone who I knew I would never outgrow."

The 39-year-old went on to recall how in previous relationships, he'd always find himself realizing at one point: "This ain't it."

"Here was something where I got to spend the rest of my life just trying to get better," Ohanian remembered telling himself after meeting Serena. He added, "Obviously, having a child with her is a cheat code, because you really understand the opportunity you have to speak all of that into someone who you want nothing more than the best for."

In fact, Ohanian said former president Barack Obama even gave him some "good advice" on being a girl dad. Putting on his best Obama impression, Ohanian recalled the A Promised Land author telling him: "The man you are to your wife is man that your daughter is going to see and come to expect. So, remember every time you're with your wife, you are role-modeling that behavior not just for your daughter but for whoever she's going to get to know in her later life." 

That's why Ohanian is now doing "my best work" to set an example for his little girl—including investing in Angel City FC, a women's soccer team whose story will be told in the upcoming HBO docuseries Angel City.

"All they needed was a platform to really honor their greatness," Ohanian said of the team. "This is the start of, I hope, many investments. Let me give my capital, my resources, my teams expertise to help amazing women do great things. I'm more than happy to ride those coattails."

Sharing how he and Serena, who also has part ownership in the team, are also doing their best to empower their daughter, Ohanian added, "I hope Olympia sees it."

Angel City, a three-part documentary series from HBO Original, will debut in May.
