Turns out there was some confusion all around regarding the show that was billed as “An Intimate Birthday Celebration” with the performer at Ziggy’s, according to the Winston-Salem Journal.

Ticketholders expected a concert with Kelly, but it turns out Kelly was paid to just make an appearance – a la Paris Hilton or Kim Kardashian – by Ziggy’s reps.

Kelly reportedly went on stage late, sang a few lyrics of “Bump ‘N Grind” with the audience, then turned the show over to a DJ as he smoked a cigar and drank.

Several hundred attendees were said to be livid and voiced their anger on the Internet.

Ziggy’s co-owner Charles Womack, who said he paid $25,000 for the celebrity appearance, told the paper he learned a hard lesson.

Ziggy’s posted on its Facebook page it is offering vouchers to a future show to make up for the misunderstanding.
