According to the latest report from Us Weekly, Britney Spears tried on underwear in a porn shop and stole a wig. Yup, another wig.

The pop princess entered the X-rated Hustler Store in West Hollywood ahortly before 1 a.m. on Sunday, Nov 18. Brit loaded up on naughty underwear and wanted to try them on in a fitting room. But store employees “told her they don’t allow people to try on underwear,” a source at the scene says. “She was really upset [and] looked out of it. There was nothing going on behind her eyes.”

Brit proceeded to take off her own underwear before trying on a pair of boyshorts in the middle of the store while 15 other customers looked on. FIFTEEN!!!!! (See inset with “Barely Legal’ stitched across the rear end.)

An eyewitness reveals, “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.”

As payback, “on her way out, she went up to a mannequin, snatched the wig off the head, and stole it!”
