Jennifer Aniston at 2009 Oscars

Although there was much buzz in the days leading up to the Oscars about whether or notwould attend - attend she did.

Aniston dazzled in a silver Valentino gown and Jimmy Choo sandals, exuding modern glamour as she arrived on the arm of boyfriend John Mayer.

Once inside however, Jen nervously stumbled through her lines with Jack Black as the two presented the awards for Best Animated Film and Best Animated Short Film.

Perhaps she was uncomfortable with Brad Pitt and Angelina Jolie sitting in the front row, as the cameras panned to Jolie not just once, but twice while Aniston was onstage.
