Last night, Dwayne “The Rock” Johnson appeared on Tonight Show spin-off, Lip Sync Battle, where he went head-to-head with co-executive producer, Jimmy Fallon.

The show, hosted by LL Cool J, allows its celebrity contestants to pick and choose their own tunes. Some selections may come as a surprise to viewers.

When asked about his first song choice, Johnson said, “Tay Tay.”

“Tay Tay? I’ve never heard of Tay Tay,” Fallon replied, “You can’t lip sync a song no one’s ever heard of.”

“Well believe me, your ass is getting ready to know Tay Tay,” according to the buff actor.
