Nightclub promoters are complaining that ‘Black Eyed Peas’ performer Fergie has been showing up late for performancing and partying with friends after finishing just half a set.

Several PR companies and party promoters were hawking a four-song Fergie set at Alhambra Restaurant in Chicago last week, but no such set took place. Instead—according to at least four eyewitnesses—Ferg arrived an hour late (clearly reeling from spending the day at a boozy barbecue), ordered several bottles of tequila, and made it through half a song before hopping off stage to party with friends.

Her publicity team argues that she was never supposed to perform. “This was an appearance,” they claim. “Sometimes she will get on stage and say a few words of ‘Glamorous’, but we know about every official set and this was not one.” Fans, however, were fuming about the $75 they spent expecting to see a significant lowering of the proverbial London Bridge. In an ultimate display of protest, some party-goers walked out on their bar tabs.
