While neither party has confirmed the rumors, crush-worthy costars Ryan Gosling and Michelle Williams elicited quite the ooh-la-la! reaction while appearing together at the Cannes Film Festival this week.
The two certainly looked like a -- super cute! -- couple while promoting their marriage-themed drama Blue Valentine (already garnering Oscar buzz) in Cannes. The pair seemed quite cozy together on the red carpet, and were reportedly even caught holding hands at one point!
Another detail bound to get fans talking about the rumored romance? The two share racy sex scenes in their upcoming film. "You know, those scenes were easy with Michelle," Gosling told MTV earlier this year. "We've just been through so much together, you know? They aren't gratuitous scenes."
In February, a source told OK! magazine that the two actors have been dating for months, but "respect their private lives and don’t want to go public." Gosling, 29, has previously dated Sandra Bullock, as well as Rachel McAdams -- his costar from the beloved tearjerker The Notebook. Williams, also 29, was last linked to director Spike Jonze, and famoulsy dated her Brokeback Mountain costar, the late actor Heath Ledger, with whom she had a daughter, Matilda, now 4.
Do you think Ryan Gosling and Michelle Williams would make a good couple? Chime in below!
