An arctic blast tore through the movie biz last week: In Sundance's chilly sphere (it's freezing in Park City, Utah), film stars bundled up to pimp their projects. Aaron Eckhart and Jennifer Aniston braved the cold by cozying up on the set of their new movie. But our vote for the week's coolest celeb goes to Jerry O'Connell, who does a mean Tom Cruise.
The Mane Event
This well-coiffed crew definitely put their stylists to work: On Jan. 17, Hannah Montana star Miley Cyrus was flanked by the Jonas Brothers band, Kevin, Joe, and Nick, at the after-party for the premiere of her film Hannah Montana & Miley Cyrus: Best of Both Worlds Concert. It'll hit theaters for a one-week engagement on Feb. 1. When asked about appearing as herself and alter ego Hannah Montana on stage, Miley said, ''I definitely like performing as both. But it's really fun when you get to go out and do your thing and be yourself. That's the coolest part of being in my show.''
