Kristin CAVALLARI wants to be taken SERIOUSLY and maybe dye her HAIR!

Kristin Cavallari wants to be taken seriously



Like many young actresses, Kristin Cavallari wants to be taken seriously.
Despite her good looks and party girl persona, the former Laguna Beach star actually is looking for a meaty role -- glamour be damned.


''I want to go dark -- dye my hair and do something really dramatic,'' says Cavallari, who was set to host the Cosmo Bikini Bash on Saturday at Nikki Beach. ''Kind of the way Angelina Jolie did in Changeling, when you go into yourself and really bring it.'' (For the record, Jolie didn't exactly look plain in her Oscar-nominated role of a tortured mother looking for her lost son.)
In the meantime, biding time before Clint Eastwood calls, Cavallari is content doing the films she is offered. Out this summer is the puerile romp Wild Cherry, which she describes as ``American Pie from a girl's point of view.''
``We play seniors in high school who find
something called a Bang Book -- the guys
writing down all the girls they de-virginized,'' she says. ``We turn the tables and start messing with their heads.''


Co-stars include Rumer Willis, Tia Carrere as the principal, and Rob Schneider as a dad (incidentally, the comedian's daughter Elle is also in the flick).
In between moviemaking -- alas, Van Wilder: Freshman Year went straight to video -- Cavallari likes kicking back on our side of the map.


The 22-year-old Denverite attended DJ Irie's launch party for the Gansevoort South in June, and didn't hesitate when Cosmo asked her to party on the beach and oversee Saturday's massive aerial photo shoot this weekend (the babes laid out to spell ''COSMO''; see pics in Tropical Life Style Wednesday).


''Any excuse to go to Miami, I take it. It has such a fun vibe,'' says Cavallari, who will again stay at the Gansevoort and party at Mokai and Mansion.
The trip is short, but she's one of the lucky ones who never gets jet-lagged.
''I always take the first flight out [from L.A.],'' she says. ``But I always sleep on the plane. I can fall asleep anywhere. Couch,
wherever. The minute my head
hits the pillow I'm out.''
