Jude Law was in chilly London yesterday after heading South to Rio de Janeiro to party at Carnival. The actor took advantage of his newly single status during the trip, going shirtless and even planting a playful kiss on an older woman. Sienna Miller is reportedly moving on from their relationship with new guy Tom Sturridge, and Jude is also staying social in the wake of their split. He made the rounds at the Oscars afterparties, where he was spotted sharing friendly chats with Gwyneth Paltrow and Cameron Diaz. Life hasn't been all play and no work for the star, though, who was also shooting Contagion in San Francisco just a few weeks ago.
