Chef Jamie Oliver was once Jennifer Aniston’s birthday present to Brad Pitt

Jennifer Aniston went completely crazy for Brad Pitt‘s milestone anniversary when they got married in 2003 — and gave him a surprise visit from Chef Jamie Oliver as his great gift.

The British culinary genius recently opened up about the time he was flown in to cook for Brad’s 40th birthday, explaining how he initially hung up on the ‘Friends’ star three times, thinking it was a joke, before she eventually broke through through their agents.

Oliver says he usually skips cooking for celebrities — but he makes exceptions for people he admires. So when Jen asked him to surprise Brad — who was apparently a big fan of Jamie’s “Naked Chef” show at the time — he jumped at the chance.

Jamie says everything went off without a hitch — and Oliver has nothing but love for the now-exes … who he says he’s kept in touch with. He says he saw Jen recently and had nothing but kind words for her.

Oliver’s wife first spoke about this dinner in 2014 … joking about how awkward it was for her to make small talk with the A-list crowd … which also included Jen’s “Friends” co-star Courteney Cox.
