Taylor Swift might have a little Stephen Colbert obsession.

In a preview of her upcoming appearance on Global’s “The Late Show”, the singer shared a clip from their conversation, in which the host asks about the inspiration behind her song “Hey Stephen”.

“Is the song ‘Hey Stephen’ about me?” Colbert asks, point blank in the interview.

Swift, clearly a huge Colbert fan, replies: “No, Stephen… I mean I first recorded that song in 2008 I think I was like 18,” as the talk-show host says: “I was also a younger age.”

It turns out Swift knows exactly how old Colbert is and exactly where his office is, but insists the song is still not about him.

“It’s just the power of music, Stephen,” Swift tells him. “Good songs, they just make you feel like it’s about you.”

She adds that it was really fun to record the song again for her new album Fearless (Taylor’s Version).

“To get me back into the same headspace as when I wrote it, I just wanted it be really authentic as an experience, so I dug out my old mood board,” she continues, pulling out a big collage made up of pictures of the host.

“Taylor, those are all pictures of me,” Colbert says, to which she dryly replies and points to one photo, “No. This is a pizza.”

In truth, Swift’s song was inspired by her crush on Love and Theft’s Stephen Barker Liles, who toured with her in 2008, according to Pop Sugar.

“The Late Show With Stephen Colbert” airs weeknights at 11:30 p.m. ET/PT on Global.
