LOS ANGELES, California (X17online) - On Sunday, the day Brad Pitt usually spends with Angelina and his family, Brad attended an award screening of his film, Inglourious Basterds solo before heading out for margaritas and Mexican food at the cool but casual El Compadre in West Hollywood with Quentin Tarantino, some of the other Basterds and a mystery woman!

"We were kind of surprised that Angelina wasn't with him," a photog tells X17online. "Sunday is the day he usually spends with Angie and the family, and he spent the entire afternoon at a screening and then a party afterward. And with awards season coming up, you'd think she'd want to be there to support her man in his Oscar bid!"

But Brad seemed perfectly happy at the party without her, staying at the eaterie for over an hour. "Brad seemed to be having a good time with everyone and didn't appear to be in too much of a rush to get back home," says the snapper.

We're sure this woman is no threat to Angelina, but what would she say when she sees her man with his hands on another girl?
