Britney Spears visited the X-Rated Hustler Store in West Hollywood last week, just before 1. Brit picked out different types of underwear then headed to the fitting rooms. Of course, she was stopped when the store employees 'told her they don't allow people to try on underwear,' an eyewitness told Us Weekly:

"She was really upset. She looked out of it. There was nothing going on behind her eyes. The employees kept saying 'Don't change out here!' She's just like, 'Well, I couldn't take them in the fitting room!' It was like dealing with a child. The staff told her she had to pay, and she rolled her eyes, but paid with a credit card, on her way out, she went up to a mannequin, snatched the wig off the head, and stole it!"
