Brad Pitt was surrounded by security as he headed out of the John Anson Ford Theater in LA last night. He caught a performance by Chris Cornell on his solo night out, since Angelina Jolie is reportedly in Cambodia shooting her ad campaign for Louis Vuitton. Brad's been taking care of things at home while his partner is away, and he ventured out with his youngest kids, Vivienne and Knox, last week. The threesome had a fun park day with Brad Pitt, Vivienne, and Knox all enjoying the warm weather on the slide, swings, and in the sandbox. Brad and Angelina will get to experience more fun in the sun when they head to the Cannes Film Festival to debut Tree of Life and Kung Fu Panda 2 next week. The family might need to find a new place to stay though, since his and Angelina's mansion in nearby Brignoles is apparently undergoing extensive renovations.
