Shia LaBeouf and his girlfriend, Carey Mulligan, shared a kiss as they walked around and picked up a build-your-own-volcano kit on Tuesday (December 15) in Sherman Oaks, Calif.

LaBeouf and Mulligan have been spotted getting around L.A. using public transportation.  Even celebrities need to get around town.  No limo for these two.  LaBeouf had his license suspended for a minimum of a year due to his “refusal of chemical tests” (breathalyzer test) after his accident last July.  

Carey is nominated for Best Performance by an Actress in a Motion Picture – Drama and has some stiff competition, going up against Precious‘ Gabourey Sidibe, Helen Mirren and Emily Blunt!  More photos after the jump!!
