Angie was seen Saturday with at least one of her kids -- her daughter, Shiloh -- at the Renaissance Pleasure Faire of Southern California in Irwindale.

Witnesses tell us there were other kids with Angie and Shiloh -- unclear if they were siblings or just friends.

We're told Angie and the crew were flanked by a massive bodyguard who followed them around the event -- can't ever be too careful.

Still, the people we spoke with say Angie seemed happy -- smiling and talking to staffers and other costumed folk -- while chomping down on what appears to be a turkey leg.
