MTV Buzzworthy Blog › Brittany Murphy

If you're seeing double, you're not alone. Above, the freakishly similar (blond-haired, dimply-cheeked) faces of Brittany Murphy -- the girl from Clueless who dated Ashton Kutcher! -- and Chelsea Staub -- the Disney wunderkind who played the beeyotch in Bratz: The Movie. (Seriously, it's like looking into a mirror -- a really weird mirror that shows you pics of moderately famous people with nearly-identical pointy chins instead of yourself.)

'Course, in addition to looking uncannily alike, Britney and Chelsea also seem to share the acting bug. But while Brit's been staying under the radar since 2006's Happy Feet, 20-year-old Chelsea's on the verge of blowing up Demi Lovato/Selena Gomez style! Girl just landed herself the role of Stella Malone in the new Jonas Brothers' TV series J.O.N.A.S.! (Love the name, guys!)

Oh, and in case you weren't jealous enough of Chelsea already? The Phoenix native -- who also kinda looks like Ashley Tisdale-slash-Stacy Keibler? -- is rumored to have recently dated Joe Jonas. There's no solid proof, natch, but there IS solid circumstantial evidence (in the form of reports that the "couple" once "shared a bag of potato chips" and briefly held hands) which, if you ask us, is more than reason enough to hate her/wish you had her life.

Welcome to Hollywood, Chelsea. You'd better believe we'll be watching you...
