Well, you'd think they'd leave in the same car together, but we still think something is up with these two -- and we're not the only ones!

Uma Thurman and Quentin Tarantinto went to dinner at Mr. Chow in Los Angeles last night, and fresh from her split from Arpad Busson, we have to wonder if this was just a friendly meeting or a hot date! After their meal, the two shared a warm embrace before getting in their cars (he rolled up in his yellow mustang, she had a driver), and when Quentin arrived, we noticed that he was holding a binder, so it seems as though there could be yet another collaboration in the works!

The duo first worked together 20 years ago on Pulp Fiction, and while Uma has always been referred to as the director's muse, Us Weekly reported last month that the two "had a thing and got together again recently." A source added, "There has always been an attraction. She has indulged from time to time, and that's how their relationship has always worked."

They seemed awfully cozy together at the Cannes Film Festival last month ... but do you think they are actually together?
