Serena Williams Makes Surprise Cameo In Super Bowl Performance

While Williams was enjoying Green Day from the crowd, it wasn't too long ago that she was up on stage. At the Super Bowl halftime show, the tennis star made a cameo during Kendrick Lamar's historic set. The rapper is the first rapper to headline the Super Bowl solo and now holds the title of the most-watched Super Bowl halftime performance of all-time.

Williams' involvement in the Super Bowl halftime show came as a shock to fans since they weren't expecting the tennis star to make a cameo during Kendrick's “Not Like Us” performance. She was seen c-walking during the show, a move that she was criticized for back in 2012 when she celebrated her win against  Maria Sharapova at the Olympics at Wimbledon court.

However, this time, it wasn't just the c-walking Williams received backlash for. She was accused of being petty by getting involved in the show since her past romantic history with Drake, who “Not Like Us” is aimed at.

Her husband, Alexis Ohanian, whom the tennis star shares two daughters with, came to her defense online. He called the show “fantastic” and how it symbolizes more than what people are scrutinizing Williams for.

“Some of y'all have no idea how criticized Serena was for this same dance at Wimbledon 13 years ago and it shows…. This is bigger than the music,” Ohanian said in another post on X.

“That there my baby daddy and husband. Always got my back. I Love you,” she responded to his post on X. “Gosh I’m so late to the game (I’ve been sick) & busy investing in billion dollar companies and running @WYNbeauty… def not dancing to be petty lol.”

She continued, “I think I proved 23 times over (not counting 4 gold medals) that I simply don’t have time for petty. All love and respect always nothing negative here.”

In a recap video of the event which shows Williams getting ready for the show, she shared how she was contacted by her fellow Compton native.

“When Kendrick and team called and was like ‘we’ve been trying to do something forever, what about this? We loved your crip walk at the Olympics after you won the gold medal,'” Williams captioned the video.

“I’m like Super Bowl? Are you serious? When in the world would I ever be able to dance at a superbowl? (Never) let’s do it!” Williams added. “I knew my winning dance after the @olympics would pay off one day. End of story.”
