Mischa Barton, stepping out to lunch in West Hollywood with her new beau, Rooney guitarist Taylor Locke. Later, the actress stopped by a memorial concert for filmmaker Brandon Schantz at the Roxy, where Locke's band performed. Barton headed straight backstage – then took her spot in a booth to get into the music, clapping with her arms above her head at the end of each song and bopping her head to the music. After the show, Barton retreated backstage again before coming out with her beau, holding him around the waist and kissing him on the lips.
