Rachel McAdams and Michael Sheen Holding Hands Pictures

Rachel McAdams and Michael Sheen held hands on the streets of London today. They stepped out to grab a taxi and, when they couldn't get one, hopped on the tube. Rachel and Michael have been spending a lot of time overseas lately since they've both had work to do in the UK. Rachel filmed Sherlock Holmes: A Game of Shadows with costar Robert Downey Jr., while Michael is starring in Hamlet. November was a big month for the couple, since Rachel also rang in her 33rd birthday and Michael's Breaking Dawn Part 1 had a huge opening at the box office. We marked her birthday with a look back at Rachel's best movies and the Twilight excitement with a roundup of Robert Pattinson and Kristen Stewart's sweetest moments.
