Serena Williams Just Dropped Her ‘Ins & Outs’ List for 2025—And One ‘Out’ Has Fans Spiraling

Serena Williams serves up some major style and tennis skills but now she’s serving up her "ins and outs" for 2025—and one of them is sparking a major debate on the internet.

In a recent video, Serena goes through a list of things that are “in” or “out” for the year. Her “ins” ranged from wearing makeup while working out to letting her daughter Olympia do her makeup to opening a business. On the flip side, her “outs” included playing it safe, sleeping in makeup and calling an opponent’s ball “out” when it was actually in. But it’s another "out" in particular that’s really getting people talking: sleeping with socks on.

In the video, Serena declares that sleeping with socks is definitely “out” and adds, “How uncomfortable is that?” While she had some supporters (one even commented, “Serena, sleeping with socks is definitely OUT”), many fans sounded off in the comments, passionately disagreeing with the tennis star.

"I love me some Rena but I don’t like my feet cold," one fan shared. Another wrote, "Sorry lady, I need my socks." A third person chimed in, "Yeah, I will not be sleeping with my feet cold—keeping those socks on as I sleep is mandatory, I said what I said." And a fourth added, "Socks are MANDATORY to sleep in," with another fan saying, "I like to sleep with socks, come onnn Serena."
