When asked which celebrity she'd want to take to a prom, Taylor Swift names a few dream choices.

"It would be a group, and it would be a really fun group," the singer, 21, says on the Jan. 3 episode of the Rachael Ray show. "Because all these different reasons. Well, Katy Perry would be so much fun. She’s just like crazy fun and like spontaneous."

Swift continues, "Diddy has always been very nice to me. Justin Timberlake is the same way, he’s really funny. And, Sheryl Crow is really down to earth and really cool. And like, J. Lo would be a really good dancer!"

Noticeably absent from her list is one star she's been seen with recently: Jake Gyllenhaal.
