Kate Beckinsale joined a friend, her daughter Lily, and their dog for a walk in LA yesterday. The gang trekked through the hills before finding a grassy spot for a bit of relaxing. Kate is back in California following a stint away working on Underworld 4, which is the first in the series her husband Len Wiseman is not involved with between directing or writing. It seems she and Len may have another project in the works, though, since Kate's tee has started speculation that they're expecting. Whether or not Lily has a little brother or sister to come, she already welcomed someone new into her life. Lily was spotted recently hanging out with her dad Michael Sheen and his girlfriend, Rachel McAdams. Michael just arrived back on the West Coast for a premiere of his and Rachel's Midnight in Paris, and he spoke to us about how lovely their relationship has been since they met on the set last Summer.
