Actress Piper Perabo had no problems playing a lesbian in her new movie IMAGINE ME AND YOU - because she has a huge crush on Diane Keaton.

The COYOTE UGLY star plays a married woman who falls for Lena Headey in the new love triangle film, and admits the desire she developed for Keaton on the set of another new movie, BECAUSE I SAID SO, helped her understand what it's like to crave another woman.

She says, "I developed a huge crush on her (Keaton). She's fantastic and she has a great a*s - at 60.

"I don't even have an a*s like that. She's f**king awesome. She's dazzlingly erotic and magnificent. She has beautiful hands."
