Ashley Greene: Demi Lovato and I Are Like Jen and Angelina

What would Angelina Jolie say?

Ashley Greene has heard a fair share of rumors about herself since making her mark on the "Twilight" film franchise, but the 24-year-old star prefers not to comment on them, telling Allure magazine's November issue that if she did, she "wouldn't have time for my day job."

But Greene is willing to open up about her supposed feud with Demi Lovato, with whom she shares an ex-boyfriend, Joe Jonas. In fact, Greene squashes any rumored bad blood between the two starlets, telling Allure that the pair always got along.

"I'm really happy that she's doing well," Greene says of Jonas' 19-year-old songbird ex, who split from the singer shortly before he hooked up with Greene. "She and I never had a problem with each other, but, you know, it doesn't go away. Jen Aniston still gets asked about Angelina Jolie."

Calling it quits with Jonas in March, Greene says she's casting a wide net when it comes to finding her perfect match.

"I go through stages," says Greene, who has been linked to Twilight's Jackson Rathbone and Kings of Leon's Jared Followill in the time since breaking things off with Jonas. "Randomly, I'll be attracted to a crazy rocker with tattoos. And I find that I'm extremely attracted to ambition and wit. If it was appropriate to date Michael Sheen, I would, but he and his girlfriend [Rachel McAdams] are so cute."

"And maybe this is 'You want what you can't have' -- Neil Patrick Harris," she tells Allure. "And, oh, Cooper Anderson….[I mean] Anderson Cooper. I'd be all over that."
