Jennifer Aniston traded her tea cup for a container of Jello yesterday on the LA set of her directorial project Project Five. She was first spotted working on the piece Tuesday, and her final product will eventually be combined with four other shorts to create one full movie to air on Lifetime later this year. Jen's getting her feet wet behind the camera before lensing The Goree Girls in a few months, but all the filmmaking apparently hasn't put a damper on her social life. Jennifer may be dating Bradley Cooper at the moment, as they've reportedly been hanging out lots on the West Coast, since his recent parting from Renée Zellweger. Her rep has apparently denied the rumors that Bradley and Jen, who were first linked in 2009, have reunited romantically. However, there's always lots of interest in Jen's love life, whether she's seeing Bradley or getting linked to George Clooney.
