Well, maybe that's a slight exaggeration, but his 5SOS bandmates totally called him out on his celeb crush and it all went down in the cutest way possible.
When the guys chatted with ET earlier this week, Calum Hood revealed that Luke "writes fan mail," adding, "He actually writes poems as well - 'My Dear Selena.'"
Ashton Irwin piled on, saying, "He has a love shrine in the kitchen!" Michael Clifford added, "Yeah, that love shrine is so weird!"
OMG, they totally wouldn't let up!
Luke set everything straight, joking, "No, I'm not actually that obsessed with Selena. Galena Somez? Oh! You mean Galena Somez. Galena is kinda hot."
Last year, Luke had Selena listed on his backstage tour rider demands, and earlier this year, a photoshopped pic of Luke and Selena made the rounds, with rumors flying they were dating after they attended Taylor Swift's birthday party.
