Selena revealed on interview with Ryan Seacrest on E! Special, that her celebrity crush is Bradley Cooper, but since he is a lot older than her, she said her age-appropriate crush is Logan Lerman.
Logan reacted and said in an interview with Access Hollywood on "Percy Jackson: Sea of Monsters" press:
''I've never met her before, but that's really nice," Logan said in an interview. "She's very pretty. I've very flattered.''
