The “Can’t Stop the Feeling!” singer relived the silly incident, which also involved comedian Jimmy Fallon, during an appearance on “The Tonight Show” on Thursday.
Fallon brought up a golf tournament in Las Vegas where he had played with Timberlake against Kelce and the NFL player’s Kansas City Chiefs teammate Patrick Mahomes.
After Fallon surprisingly nailed a bunker shot, all four men went wild.
“Even the other team was rooting for me. That’s how bad I am,” Fallon said after showing a video of the moment.
Timberlake said what happened next made “my life flash before my eyes.”
Kelce ran towards the singer to do a celebratory side bump, Timberlake said, “and I was like, he’s doing it! I have to do it!”
He added, “And I forgot that he weighs like 80 pounds more than me.”
The video shows Timberlake taking a tumble after making contact.
He must have gotten the hang of it at some point. In another video online of Timberlake golfing with Kelce at a 2022 tournament in California, the two seemed to have their celebration routine on lock.
One commentator noted, “Kelce could hurt him if he jumps too hard!”
