Selena Gomez's Top 5 Celebrity Crushes

The singer, who has been known to have a few crushes, reveals her latest.

-- intro: Selena Gomez doesn't only have eyes for Justin Bieber.

The singer is known to have a number of celebrity crushes. She revealed the latest Wednesday on “Jimmy Kimmel Live”: her “Rudderless” co-star Billy Crudup.

Gomez, 22, told Kimmel that long before she ever knew they would work together, she fell hard for the now 46-year-old actor after seeing him as guitarist Russell Hammond in 2000's “Almost Famous.”

"I had a crush on him," she admitted, giggling. "I went through my whole ‘Almost Famous’ phase, so I was like Penny Lane for a good month. I wore the outfits and had the hair and the glasses.”

After learning she was going to be cast with him, Gomez said, “It took me a minute at first, because I kind of had a little bit of a crush on him.”

Though she never told Crudup about her secret crush, the cat is clearly out of the bag. "Well, evidently I'm telling him now,” she said. “I don't have to do press with him anymore, so it's fine.”
