"Angelia was unrecognizable at first because she's so, so skinny," an eyewitness at The Gap told RadarOnline.com. "She purchased two complete outfits right off the mannequins, head to toe, the shoes and everything. Then she bought a couple Junk Food t-shirts, one was a Superman emblem and a bunch of Gap watches for all the kids. She probably spent close to $500.
