Jennifer Aniston has a big date... with Oscar. The busy star, who's currently schmoozin' at the Sundance Film Festival, will make her very first Academy Awards appearance as a presenter at this year's show. Since the lights went out on Friends in 2004, Jen has been trying to transition from TV to movies. Two of her flicks were recently released -- Rumor Has It... and Derailed -- but they were widely panned by critics. Next year's Friends with Money is said to be better. No word yet on The Breakup, which is her movie collaboration with new beau Vince Vaughn. But it's going to be hard to compete with the chemistry between Brad and Angelina in Mr. and Mrs. Smith. Wowsers.Other Oscar presenters include Jamie Foxx, Hilary Swank, Luke Wilson, Jessica Alba and Morgan Freeman. Gear up for the March 5th event by visiting Oscar headquarters where you'll find Oscar quizzes, games, gossip, fashion and more.
