Shia LaBeouf and Carey Mulligan decided to do something special to mark their first Valentine's Day as a couple, renting a boat called the Lady Hornblower for a sunset cruise near LA. An attendant was even on hand to serve the couple wine and snacks, which Shia sweetly fed to a newly-blond Carey, before they wrapped things up with a little under-a-blanket cuddling. The duo hasn't been shy about showing off their love after meeting last year on the set of Money Never Sleeps. Their costar Michael Douglas apparently unsuccessfully advised them against getting romantic, saying in a recent interview, "I warned them, 'Don't ever do that.' But they are an item and they are having a great time."
