Angelina Jolie had a "massive fit" after learning Natalie Portman had personally asked for Brad Pitt to play her older lover in a new movie.

Jolie, 33, is said to be jealous of the Closer star.

"Angelina had a massive fit and was shouting her head off. She accused Brad of flirting with Natalie," a source said.

"Angelina can`t help but feel threatened. Brad knows how jealous she gets but won`t stop saying how gorgeous and intelligent Natalie is. He keeps saying she is `cute as a button.`

"Angelina worries about karma. It`s eating her up and we`re sure the cause of a lot of the rows is her not quite trusting Brad."

It was recently reported that Pitt and Jolie are planning to adopt a child from the Philippines.
