Jennifer Aniston has told friends that she feels betrayed by Jamie Oliver.

The actress is furious after learning that the chef has agreed to cater for Brad Pitt and Angelina Jolie's forthcoming wedding.

A source told The Mirror, "Jennifer considered Jamie to be a friend so when she saw pictures of him having a cosy dinner with Brad, Madonna and Guy Ritchie in London's Locanda Locatelli this week, she was surprised.

"But then she was told that the subject of Brad's wedding came up. She heard that Jamie was keen to get involved in cooking up a feast for the guests so it's natural that she'd find that hurtful."

Aniston and Pitt both became friends with Oliver after enjoying his Naked Chef series, and jumped to his defence after his restaurant was panned in 2004.

"Jen has just been getting things back on track when she found out about Angelina's pregnancy," the insider added. "That was obviously devastating and now seeing people choose Brad's friendship over hers isn't helping."
