Sienna Miller landed at Heathrow Airport in London this morning after catching a flight from LA last night. She traveled in a cute Fall cape, showing off the style that secured her spot as a best-dressed Brit. Sienna also made the cut for one of the hottest bikini moments of the year, but the news that nabbed her the biggest headline was her reunion with Jude Law. The adorable on-again couple are getting into the holiday spirit as they prepare to ring in 2011, which is already shaping up to be a good year for the duo. Sienna is set to star in a new film, while Jude will return to the big screen with his Sherlock Holmes sequel.
