Andy Roddick and Serena Williams have been friends for decades now. The duo have known each other since their formitive years as they trained together at Rick Macci’s tennis academy in Florida.

Roddick was one of the tennis players to lead the wonderful tributes after the 23-time Major winner Williams brought the curtains down on her stellar playing career.

The 2022 US Open was Williams' last swing on the court and the American lost to Australia’s Ajla Tomljanovic 7-5, 6-7 (4), 6-1 in the third round.

Roddick highlighted that both the Williams sisters are fun to be around and the lighter side of their personalities often gets neglected.

"I don’t think people see enough of the lighter side of Venus and Serena. They’re such a joy to be around when they’re not in ‘go mode.’ We’ve celebrated people’s competitiveness over the years with the greats of all time. Unfortunately, I don’t think we’ve given them the benefit of the doubt to have those kinds of same competitive moments," Roddick said during an interview with Fansided.

Roddick and Williams filmed a Lip Sync Battle together in 2018, just days after the latter's controversial US Open final against Naomi Osaka. In a 2021 podcast, Roddick divulged the details of how it all went down.

Andy Roddick also recently revealed that Williams took time out of her busy schedule to pay him a visit after he had his first child with wife Brooklyn Decker.
