Be still our hearts. Ryan Gosling and Michelle Williams clasped hands this evening at the Cannes premiere of Blue Valentine. Earlier in the day the duo killed us with their photo call chemistry, and now there's even more eye candy. He traded in his more casual daytime look for a sharp tux while she glowed in her flowing gown. Could all the hand-holding please mean something — kidding, mostly. Ryan and Michelle clearly have a dear affection for each other, and we can't help but dream that it could translate into a real life love.

Ryan and Michelle were once again joined by their onscreen daughter Faith Wladyka, whom Ryan twirled around during her big red carpet moment. He's so cute and playful with his 6-year-old costar, whose dress held some fairytale wisdom to celebrate the unconventional love story. Harvey Weinstein came out to honor the film, which his production company picked up soon after its Sundance debut. We'll be adding more photos as they come in, and catch up on all our Cannes coverage here!
