Gordon Ramsay is said to have signed a six-figure whopper of a deal to appear in a Burger King advert

A TV insider told The Sun newspaper of the deal: "As someone who has a reputation for being fiery, he seemed like the perfect choice for a restaurant whose products are famous for being flame grilled.

"And the advert's storyline is believed to based on his distinctly 'bombastic' style of operating, which is evident in his many TV shows."

According to The Reading Chronicle newspaper, Gordon was seen filming on July 8th, outside one of the eatery's restaurants near Reading Football Club's Madejski Stadium.

The Hell's Kitchen star - who is estimated to be worth £176 million, according to Forbes - is a household name in the UK and US, where he co-hosts MasterChef US.

But Gordon recently admitted he struggles to cope with the "non-stop attention" that comes with fame, especially Stateside.

He told The Times newspaper: "Fame brings nonstop attention. There's nowhere in the world where I'm not recognised, but America is a different beast. I can put on a cap and dark glasses in the UK, but over there, the moment you open your mouth they recognise the accent and you're screwed.

"I don't give a f*** what the critics say. I've been criticised more than any chef on the planet and I've developed the skin of a rhinoceros.

"But I'll always defend my team if they've been hurt by a flippant remark or derogatory comment. You have to go into bat for your team, right?"

Gordon also recently admitted he has only dined at his eponymous Michelin star restaurant twice - because it is "too posh" for him.

He said on The Savoy Originals podcast, he said: "There's a very fine line, running it or indulging in it.

"I've only had dinner at Restaurant Gordon Ramsay twice in 25 years.

"Once was for [daughter] Megan's birthday, and the second time was with Bradley Cooper when we were together for the film Burnt.

"It's not my style. It's too posh for me. It sounds weird, right? You built the place and it's like, 'I'm not built that way. I can't sit there with that level.

"It's bloody intimidating and it's a very special moment for the guests, not for me, because I'm a giver - I'm not a receiver."
