Bradley Cooper’s already denied dating Jennifer Aniston, but the He’s Just Not That Into You costars were spotted having a late-night dinner à deux last night.

The two shared pasta, steak and salad at Il Cantinori restaurant in Manhattan. There was no hangover for these two…they sipped Pellegrino water instead of alcohol.

The restaurant’s manager says Jen is a frequent customer, but this is the first time she’d brought in her new boy-toy.

“They were very nice and chatty,” says the manager.

This isn’t the first time these two got romance rumors swirling…

They were first spotted together at a party in May for her flick Management.

Jen’s currently in NYC filming The Bounty Hunter with Gerard Butler.
