Katie Holmes and Tom Cruise are back in LA following a stint in NYC, and she had a busy afternoon running errands yesterday while he reportedly headed to the Paramount studios for a meeting. She kicked things off, stepping out to purchase armloads of flowers (possibly for Suri's upcoming fifth birthday on Monday), but then Katie changed outfits in order to hit up the Marc Jacobs store in Beverly Hills. Tom recently wrapped up shooting Mission Impossible: Ghost Protocol and is now prepping for his next project, Rock of Ages, with new addition Russell Brand. The big screen adaptation of the musical will present a new challenge for Tom with all the singing numbers, and he's apparently hired Axl Rose's vocal coach to help. Tom's still lining up even more work and progress is moving along on another movie. He's in talks to star in Tron director Joseph Kosinski's next movie Oblivion, playing a soldier stuck in a post-apocalyptic-type universe.
