Vanessa Hudgens Sings for Sa5m

Vanessa Hudgens chats away on her iPhone as she exits a recording studio on Thursday afternoon in Westwood, Calif.

The 20-year-old Identified singer was recording songs for her upcoming movie, Bandslam. Vanessa plays Sa5m, a 15-year-old girl who has a stuttering problem but breaks out of her shell when she gets involved in a battle of the bands competition. The movie also stars Alyson Michalka and former Friends star Lisa Kudrow.

Bandslam hits theaters in July 2009. Vanessa wore Wildfox Couture‘s “Light Feather” raglan tee.

FYI: It’s also possible Vanessa was leaving a legal depositon for a 2005 agreement between her and former manager Johnny Vieira.
