Megan Fox pumps her first in the air Jersey Shore-style while visiting the Book Star store on Sunday afternoon (April 25) in Studio City, Calif.
The 23-year-old Transformers actress was accompanied by her long-time boyfriend Brian Austin Green and his son Kassius, 8.
Last weekend, Megan came out to support Brian while he raced (and won) the Long Beach Grand Prix for the Toyota Pro/Celebrity Race.
