He's known for the odd innuendo in his recipe books, and even admits to writing some "pervy" cooking tips.

But celebrity chef Jamie Oliver, 42, revealed he only allows his children to swear during the festive period, while also confessing he's banned his family wider family from attending the traditional Christmas dinner, the Daily Mail reports.

Talking on Sky One's The Russell Howard Hour on Thursday, the Naked Chef said he doesn't allow his children to use expletives all year round but makes a one-minute exception at Christmas.

Oliver has five children, Poppy, 15, Daisy, 14, Petal, 8, Buddy, 7, and 16-month-old River, with wife Jools.

Of his own profanity, he said: "I love it but as a dad, I don't like it. I say, 'How do you know that?' My boy [Buddy] makes them rhyme as well."

Although Oliver doesn't like his kids using inappropriate language, he has been known to throw in a touch of innuendo while writing recipes for some of his cookery books.

He added: "I do write a couple of pervy recipes in each book. The best food to arouse? Light, not spicy. Something soft and easy."

Oliver is shaking up tradition once more this year in what he calls a "controversial decision".

The chef has put his foot down with his wider family, saying he'll only be dishing up the turkey and trimmings to his own brood.

He won't be completely off-duty for the big day, adding: "For 15 years I've done the big Christmas and everyone's come to us; there's like 30 people.

"But two years ago I said, 'This feels like work' so last year and this year it's just my mob, the kids and my missus."

Not to worry for those forgotten family members, as Boxing Day will remain an open invitation.

He added: "The next day we do it for a big mob but it's cheeses, cold cuts, pickles, we buy interesting things and make a couple of bits - I knock out some nice bread and that's about it."
