Further proof that Shia LaBeouf and Carey Mulligan are more adorable than a litter of golden retriever puppies snoozing on a Hello Kitty pillow: After the "Money Never Sleeps" premiere at the Cannes Film Festival on Friday, the actor made sure his honey didn't catch a chill by giving her his tuxedo jacket to wear. A little later on, he was spied "rubbing her back and leaning down for kisses" as they chitchatted with fellow guests at the post-screening shindig, reports Lainey, who also witnessed another lovey-dovey moment between the two. Seems that, as they made their exit from the party, Shia stopped at the top of a staircase, bent down, and, in a gentlemanly display (and a nod to Cinderella), helped Carey put her shoes back on her aching tootsies. "I was thrilled when I realized they were going to be an item," "Money" director Oliver Stone tells People. "It just made their scenes together all the better -- especially the love scenes. Let's just say it was no stretch for them."
