He’s the star of the hit Food Network show, “Dinner: Impossible.”

Now Chef Robert Irvine is in hot water over charges that he cooked up his resume.

In an article headlined, “TV Chef Spiced Up His Past Exploits,” the St. Petersburg Times says Irvine’s claim that he was knighted by Queen Elizabeth is simply bogus.

Buckingham Palace says Irvine is not a knight, and the chef now admits he made it up.

INSIDE EDITION spoke on the phone with Wendy LaTorre, who invested in a restaurant he was trying to open in Florida.  When asked if Irvine had told her that he was knighted by the Queen, she says, “Yes, he made me introduce him that way.”

The newspaper is also raising questions about Irvine’s claim that he “assisted in the creation and painting of the royal wedding cake” when Price Charles married Diana in 1981.

The chef who actually created the cake told the St. Petersburg Times: “He most certainly was not involved with me in making or baking the cake.”

Irvine’s official resume also claims he prepared state dinners at the White House, something a White House spokeswoman says is not true.

Irvine has not commented on the controversy, but a Food Network spokesman told INSIDE EDITION:

"It's unfortunate if Robert embellished the extent of his culinary experiences.  We are investigating the matter and taking the necessary steps to ensure the accuracy of all representations of Robert on Food Network."
