It's one of our first sightings of Angelina Jolie since she gave birth to twins Knox and Vivienne nearly three months ago! What brought her back into the public eye Friday night?

Angie was spotted arriving at Il Buco restaurant in NYC, looking as gorgeous as ever. And according to a source, her 'Changeling' director Clint Eastwood was there with her for a dinner party.

Just two days ago, Angelina, hubby Brad Pitt and their six children returned to the U.S. for the first time since welcoming little Vivienne and Knox to the family!

The power couple flew into NYC for the premiere of Angie's new Eastwood flick, 'Changeling,' taking place at the New York Film Festival on Saturday.
