Singing a Taylor song? You get a dollar! Comedian Billy Eichner took his infatuation with Taylor Swift to the next level when he belted out a song that he created just for her during Conan on Wednesday, Dec. 3.

"She's brilliant and the most popular singer in the world right now!" Eichner, 36, exclaimed to the late-night host.

"There are so many disturbing, upsetting things happening in our world right now in our country, internationally, but Taylor Swift is writing about the most important topic, which is what happens when your boyfriend doesn't text you back?" Eichner cracked. "And I think that's so essential, Conan."

The Parks and Recreation actor is so fascinated with Swift (will he be her next celeb BFF!?) that he actually penned a song called "Glitter and Ribs" for her last year — from her point of view. Swift has yet to record the tune, so Eichner — next set to star alongside BFF Julie Klausner in new Hulu comedy Difficult People — decided to perform it himself during his Conan appearance.

"He was a boy / I was a girl / What more do you need to know?" he sings on stage. "With burgers on the grill and sparkles on my eyes / He served me a fib with a side of lies."
