The singer - who will be releasing her debut country album 'Do You Know' later this year - told stunned fans at her concert in Ontario, Canada, that she has a unique digestive system.

She said: "I do pass gas a lot. But I guarantee you it smells like roses."

Jessica's country single 'Come On Over' and bid to be accepted in the specialist industry is already attracting negative reviews from critics. John Law wrote in the Niagara Falls Review: "It might be unfair calling Jessica Simpson's recent show a train wreck - at some point, a train knows where it's going. Jessica is still living in a reality show, convinced everyone is so fascinated with her personal life, they'd rather hear her talk than sing.

Referring to former 'Newlyweds' star Jessica's supposed interest in legendary singer Dusty Springfield, John added: "It's hard to take her seriously when she declares how much she loves 'Destiny' Springfield, and then performs a version of 'Son of a Preacher Man'."
