New Couple Alert: Joe Jonas And Ashley Greene???

They seem slightly mismatched -- she's the sexy star of Twilight who once posed wearing nothing but paint, and he's part of the wholesome threesome Jonas Brothers band -- but new reports are claiming that Ashley Greene is dating Joe Jonas!

We wondered why Joe Jonas would travel across the pond to attend the Eclipse premiere, and apparently he went over 5,000 miles to have a pre-premiere date with Ashley Greene, according to OK!

Joe and Ash apparently went to dinner at London restaurant The Ivy before the red carpet affair, where they walked separately, of course:



Joe has dated hot young starlets Taylor Swift, Camilla Belle and Demi Lovato, so we guess Ashley kind of fits his type. And she's been linked to hotties like Chace Crawford and rocker Kings of Leon bassist Jared Followill, so I guess Joe fits her bill too!
