Ashley Greene

Unlike her LOL costar Miley Cyrus, Ashley Greene has never aspired to be a young bride.

"I'm not one of those girls who sits at home thinking, 'By 25, I have to be married,'" Greene tells the August issue of Cosmopolitan. "Right now, I'm like, 'I'm 25 -- I need to book my next movie!'"

Greene points out that her "parents have such a beautiful marriage," which is why she's "not someone who takes it lightly. I'm not going to get married until I know I'll be with someone forever."

When it comes to dating, The Apparition actress -- who's still going strong with Broadway star Reeve Carney -- says her taste in men has evolved. "It's about chemistry and a connection," says Greene, whose exes include singer Joe Jonas, 22, actor Chace Crawford, 26, and rocker Jared Followill, 25.

"I've changed so much over the past 10 years. What I wanted when I was 16, I didn't want when I was 20, and that's changed to something else now that I'm 25," Greene tells Cosmopolitan. "Having a type is not for me."
