Brad Pitt and Angelina Jolie like to ''have a laugh'' with Jamie Oliver.

The British chef - who has four children, Poppy, 10, Daisy, nine, Petal, three and Buddy, two, with wife Jules Oliver - admits he and the Hollywood legends get together on a casual basis and when they do they enjoy having all their kids play together.

Jamie said: ''Brad watches a lot of cooking shows, but he hasn't asked me for any lessons yet, so no.

''Brad and Angelina have a lovely family, with kids all over the place like ours.

''We see them about once a year because we have mutual friends. When they're doing something over here, we get together and have a laugh.''

However, he is not sure if he will be invited to their wedding - and doesn't even know when it will happen.

He added in an interview with Closer magazine: ''Am I expecting an invitation to their wedding? No. I don't even know when they're getting married!''
