Swifties can countJack Blackas a one of them!

During The Give Back-ular Spectacular! event in Los Angeles last night, the comedian, 54, delivered an impromptu cover of a belovedTaylor Swifttrack.

In afan-posted videoon X (formerly Twitter) from the fundraiser, which was held to support members of SAG-AFTRA during the Hollywood strike, Black is seen removing his shirt and sauntering around the stage in boxers as the audience cheers him on. After his striptease, theSchool of Rockactor heads over to an attendee to ask where they’re from, to which they reply “Los Angeles.”

In a video from the event, Black takes off his shirt, wearing just some boxers, as the audience cheers after the move. He then walks down to an audience member to ask where they’re from, getting just “Los Angeles” as a hilarious response.

Then, he heads back to the stage where he asks for song requests. While he shoots one of the songs down because of the SAG-AFTRA strike, someone seemingly shouts out a track that he “knows,” and he bursts into a Swift song.

“I know that one!” he told the audience member. “Everyone knows that f—ing song.”

Black then delivered a theatrical rendition of the “Anti-Hero” chorus, while prancing from side to side across the stage and doing a backward shuffle when he gets to the “It’s me, hi, I’m the problem, it’s me” lyric.
