Jessica Simpson admitted to a flatulence problem at her show at the Avalon Ballroom in Niagara Falls on Wednesday, according to the Niagara Falls Review.

"I do pass gas a lot," she said. "I guarantee it smells like roses."

And that was the least of Simpson's faux pas, according to the Niagara Falls Review critic, who writes that it might be unfair to call the show a train wreck because "At some point, a train knows where it's going."

Simpson has recently made the move from pop to country, and the critic says "this cowgirl seems completely lost and desperate for approval on stage" which "made for a bizarre and often frustrating show."

She also declared how much she loves "Destiny" Springfield, according to the writer, when she meant to say Dusty Springfield.

The critic did have some kind words for Jessica, saying the performance was unworthy of her new album and that her "ditzy" persona is what "makes her so likable."

On a side note, the writer suggests that Simpson implied in a song dedication that ex-husband Nick Lachey cheated on her.
