Make no mistake, Gordon Ramsay does NOT approve of pineapple on pizza.

The much-condemned topping has been the focus of his wrath in the past with the outspoken chef and Hotel Hell presenter pulling no punches on the matter.

"You don't put f*****g pineapple on pizza... What the fuck are you doing?"

See? He really doesn't approve of it.

But even world-famous and award-winning chefs have to eat their words sometimes.

Gordon has gone on record - in his usual sweary style - saying he will eat an entire pineapple pizza live on Facebook.

It's a dramatic U-turn which has left his fans shocked.

But it's ultimately for a good cause.

Ramsay took to Instagram to promise a live stream of him eating pineapple pizza if he gets enough donations to the Gordon and Tana Ramsay Foundation , a fund within Great Ormond Street Hospital Charity, which cares for sick children.

"I've got a proposal for YOU," he wrote. "If we can hit 500 donations in the next 48 hours, I will eat this f**king god-awful PINEAPPLE pizza on Facebook Live.

"Don’t forget, your donation also gives you the chance to be my VVIP on #thefword . So click the link in the bio or go to omaze.com/pineapple and donate NOW!"

Not only is it for a good cause, but we imagine he'll be uttering some pretty choice phrases too.
