Rupert Friend, Keira Knightley Still Going Strong

We can't say with certainty that Keira Knightley and Rupert Friend are built to last, but they sure looked cozy on some recent nights out.

Braving snowy N.Y. weather while out for a walk in the SoHo neighborhood with beau of at least a year, Rupert Friend, Keira Knightley was somehow able to keep warm despite her thin frame. Phew.

The next night, the couple, dressed in hip attire, snuggled up together at a Chanel Beauté dinner at the N.Y. eatery, Balthazar, to celebrate the actress' new film, Atonement.

A source at the party tells us that Rupert "More Than A" Friend kept his arm around his girlfriend all night, adding that they were "very sweet together."

Looks like someone is trying to keep Keira Knightley naked all to himself. Can you blame him? Now if he'd just get her to eat a cheeseburger every so often, we'd be set.
