There's no such thing as friendly competition when it comes to celebrity chefs.
The latest dig in the Jamie Oliver and Gordon Ramsay feud comes from Oliver, who says the "Kitchen Nightmare" star is "deeply jealous" of Oliver's success.
This was in response to Ramsay's comments from last year when the Hell's Kitchen star criticized Oliver for not attending the opening of his new Hong Kong restaurant, Jamie's Italian.
Ramsay told CNBC, "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."
The 39-year-old told the Daily Mail that Gordon would do anything to bring him down and he "can't quite work out why I do what I do and why he can't do that. He is too busy shouting and screaming and making our industry look like a bunch of shouters and screamers."
Jamie's released his 15th book, Save With Jamie, which hit the top spot on the U.K's best seller list with more than 37 million sales.
Ramsay, who once referred to Oliver as a "one pot wonder," has released 21 books that have sold approximately three million copies - something Oliver says really bugs the heck out of the chef.
"You can sell a few books by luck or a moment ... but not 15 years and 37 million books. That's not luck."
Oliver didn't stop at Ramsay, though. He's also given his two cents on "My Kitchen Rules" judge Pete Evans, who recently put out a paleo book for babies. He told Daily Mail Australia, "There's a lot of BS around at the moment."
