LONDON - Brit chef Gordon Ramsay will apparently be angry after the woman who claims to have been his mistress appeared on his hit US telly show ‘Hell’s Kitchen’.

Sarah Symonds, 39, appeared on screen for a couple of seconds, sitting alone in the Hell’s Kitchen restaurant in Los Angeles.

She is seen filling out a card to give feedback on her meal, and says “OK” before the shot cuts to another scene.

Ramsay, 42, has always furiously denied having an affair with Symonds, insisting he had met her twice, both times with his wife Tana, 33.

But pals of the F Word star say Ramsay and his wife will be simmering with rage to see Symonds on their own show less than six months after she spilled the beans on the alleged affair.

“I did a double-take. You can only assume that it was a slip-up in the editing suite. You can’t imagine Gordon would have wanted her to appear,” the Daily Star quoted a viewer as saying.

Although Fox TV only showed the episode this week, it is thought to have been filmed in late 2007, a year before the blonde made her allegations.

“It was a serious slip-up letting this footage go out. It is very embarrassing for Gordon and must have been very upsetting for his wife,” a source said.

“Gordon and his team keep a tight control of who is in the restaurant. If they don’t want someone in the place, they don’t get in,” the source added.

Ramsay’s spokesman declined to comment. (ANI)
