Rachel McAdams and her boyfriend, Michael Sheen, went shopping in LA on Saturday with his daughter, Lily. Twelve-year-old Lily is Michael's daughter with ex Kate Beckinsale, and Lily seemed familiar with Rachel as they walked between shops and chatted together. Michael and Rachel, who's on the cover of June's Elle, were in California for the last couple of weeks promoting their movie Midnight in Paris, which actually brought them together as a couple last Summer during the shoot in Europe. There were enough breaks from interviewing for Rachel to run errands and pick up takeout, even sparking rumors that she and Michael are engaged by debuting a new diamond ring. Her rep, though, has since denied those stories. Rachel headed back to France today, as she's prepping to debut the film during the Cannes Film Festival. This year's cinema event is going to be even more star-studded than usual, with Brad Pitt, Angelina Jolie, Penelope Cruz, and Johnny Depp also bound for a few days on the Mediterranean!
