Hell’s Kitchen Gordon Ramsay ia about to be deep-broiled by an alleged mistress in a new tell-all.

Sarah Symonds
, who says she he had an on-and-off fling with Ramsay for seven years, is penning a book about their affair, titled Memoirs Of A Mistress – My Time With Britain’s Most Fiery Chef.

“Gordon’s time was always so limited when we met, so there was a reason why I called him ‘Flash Gordon’ in the bedroom,” Symonds, 40, told Radaronline.com.

Ramsay has denied Symonds’ allegations which became public in 2008.

“I plan to set the record straight,” said Symonds.

“I also plan to expose the truth about my appearance on the Hells Kitchen finale, which was filmed during the period that I was having an affair with Gordon, that he has since denied inviting me to.’

Symonds is no stranger to conjugal canoodling – she also had an affair with Brit author and politician Jeffrey Archer. Naturally, she wrote a book about that, too.
