Taylor Swift is sharing a version of her hit song "Anti-Hero" with Bleachers, the official stage name of Jack Antonoff.
The singer-songwriter surprised fans with the remix on Monday.
It features new lyrics from Antonoff, who produced her new album "Midnights."
Swift addressed the lyrics on Twitter, writing "Jack's version of 'sexy baby' is 'art bro' and we sincerely hope it confuses just as many people."
Fans were widely confused about her original lyrics "sometimes I feel like everybody is a sexy baby" until realizing it was a reference to the NBC show 30 Rock.
