Kesha was stopped by security over the weekend at L.A.’s Natural History Museum for unwittingly making off with a dinosaur. Sources say that the singer was at the museum Saturday for a wedding. On her way out she went to the gift store with her assistant and admired a faux dino. She held the critter in her hand and walked out of the store. On her way to the car security stopped them and asked them what was up with the prehistoric beast. Each said they thought the other paid and apologized for the misunderstanding. Kesha forked over the dinosaur and left. Problem is it was covered in glitter, so it had to endure a dino-wash.
