Gordon Ramsay has denied his alleged affair during a live cookery show.
The fouled-mouthed chef appeared on stage at the BBC Good Food Show in Birmingham and made jokes about his "bad week", the Daily Mirror reports.
"My mum is in here tonight so I'm on my best behaviour, ooh la la! Oh f*** it. I didn't do it Mum, I love you. All my family are here as well," he apparently said.
Gordon also mentioned the press stories about a mattress being delivered at his south London home.
"I have had a mattress arriving this week, everyone thought it was because I had to sleep in the basement.
"Mattress, mistress, mattress, what a load of b*******!" he said.
Gordon is due to film Gordon Ramsay: Cookalong Live tonight (Friday) for Channel 4.
