Celebrity News:

Britney hit up Sunset Tan with her new assistant yesterday, and for once, acted like she didn't want her BFFs the paparazzi, in attendance!

The freshly tanned and annoyed Brit went down a back stairwell, complaining, "This is why I wanted cops here!" Then snapped, "I'm never coming here again!"

Brit's "impromptu bodyguards" were Sunset Tan employees, who became Britney's verbal punching bags as they escorted the cranky "singer" to her car. The popwreck seems to make everyone around her an instant employee -- then rudely dismisses them! Ding dang diva!
