Melbourne, Nov 28 : Gordon Ramsay swore to a BBC cooking demonstration audience that he didn't cheat on his wife Tana with 'serial mistress' Sarah Symonds.
According to the Mirror, he said claims about the seven-year affair were a "load of bu**".
"What a week I've had. My Mum is here tonight so I'm on my best behaviour. Oh f**k it. I didn't do it Mum, I love you,'' the Herald Sun quoted him, as saying.
He laughed off the week of intense scrutiny, which has seen photographers camped out at his 9 million dollar family home.
"I have had a mattress arriving this week. Everyone thought it was because I had to sleep in the basement,'' he said.
"Mattress, mistress, mattress, what a load of bu**,'' he added.
As he left the stage at the BBC's Good Food Show in Birmingham, he said: "I want to give you a big thank you for coming. It has been a tough week.''
