LONDON: Angelina Jolie has warned George Clooney not to play any practical jokes at her wedding.

The actress is engaged to George's best pal Brad Pitt and while the couple are currently planning their dream wedding, Angelina is worried that the notorious prankster will ruin their big day.

A source told the National Enquirer, "She doesn't want any practical jokes played at the wedding and she's not kidding.

"Angie personally phoned George, warning him that she was dead serious! George got the message loud and clear – especially after Brad followed up with his own phone call, making George promise to call a truce and put practical jokes on hiatus for his and Angie's big day.

"George finally gave his word, but admitted to pals it'll be tough to resist the temptation."

However, if George does succumb to temptation and ends up playing a prank on the couple it will be Brad's fault as the 48-year-old actor previously revealed he was the one who originally started the feud.

He said: "[When we were filming Ocean's 12 in Italy] I sent a memo to the entire Italian crew, in Italian, that said, 'Dear Crew: We wish you a wonderful shoot. George Clooney asks that, this is a very difficult role for him. He needs to concentrate deeply. Mr. Clooney asks that you try not to interrupt him, look him in the eye. If you do need to address Mr. Clooney, please refer to him only as 'Daniel' or 'Mr. Ocean'.

"It went on for two weeks. He handled it gracefully, but he was becoming unnerved, I think."
