Sherlock Holmes NYC Premiere Pictures

The Sherlock Holmes: A Game of Shadows premiere in LA last night was full of famous faces. Rachel McAdams stunned in a Marchesa gown after traveling to the West Coast from London recently. She's been spending time in the UK with boyfriend Michael Sheen, and while he didn't join her on the red carpet for this event, Robert Downey Jr. and Guy Ritchie did have their leading ladies by their sides. Susan Downey showed off her growing baby bump amid news that she and RDJ are expecting a boy. Guy's girlfriend, Jacqui Ainsley, who gave birth to her first child with Guy in September, wore a gorgeous red dress to accompany her directing man. The movie hits theaters next week and will be up against Tom Cruise's Mission: Impossible — Ghost Protocol at the box office.
