Gordon Ramsay and Jamie Oliver appear to have an on-going feud. According to a report from Mirror UK, the "15 Minute Meals" star recently slammed the "Kitchen Nightmares" host for allegedly being jealous of him.

The rumored feud between Gordon Ramsay and Jamie Oliver reportedly started when the former did not attend the grand opening of "Jamie's Italian" restaurant in Hong Kong earlier this year. Gordon Ramsay also has an establishment in the same city, Bread Street Kitchen.

"Two British chefs, Jamie Oliver and Gordon Ramsay, rubbing shoulders together in Hong Kong. At least I'm here, I came to my opening, right? If you're going to open a restaurant in Hong Kong at least turn up," Gordon Ramsay said.

Gordon Ramsay and Jamie Oliver's rivalry heated up as the latter finally responded to the senior chef's remarks.

"Gordon will do anything to try and take the p**s out of me because he is deeply jealous and can't quite work out why I do what I do and why he can't do that," he said.

"He is too busy shouting and screaming and making our industry look like a bunch of shouters and screamers."

The rivalry between Gordon Ramsay and Jamie Oliver also appears to have been caused by their competing culinary books.

Jamie Oliver's "Save With Jamie" topped UK's best sellers list, making his total book sales go over 37 million. Gordon Ramsay's 21 different books have sold approximately only a total of three million copies.

"I think that really, really annoys him. Book sales are about having a deep trusted relationship with the public," Jamie Oliver explained.

"I really write my books. I don't just turn up for the front cover. I write every word, every letter and I oversee every bit of design."

"You can sell a few books by luck or a moment ... but not 15 years and 37million books. That's not luck," he pointed out.
