Jennifer Aniston is said to be feeling smug after hearing that Angelina Jolie is jealous about Brad Pitt working with Diane Kruger.

The Troy actress has reunited with Brad on the set of Quentin Tarantino's new film Inglourious Basterds and onlookers say there is a definite spark between the pair.

A US publication adds that the Friends star feels hurt after hearing Angelina fell for Brad whilst she was still married to him and feels this is perfect pay back.

A source tells Star magazine, "Jen didn't trust Diane when she worked with Brad, and now she's happy that Angelina knows how it feels.

"For her it would be the sweetest karma!"

The source adds, "Angie loves Brad and wants to trust him, but she also knows that their own love blossomed while working on a movie together.

"Now she's convinced that Diane has a crush on Brad, and she's scared something could happen."
