Kate Moss at war with Agyness Deyn

Kate Moss is at war with rival model Agyness Deyn after she became friends with her ex-boyfriend, Pete Doherty.

Kate, 34, is annoyed that the up-and-coming model, 25, is constantly being compared to her -- but the final straw came when she found out Agy has been hanging out with former boyfriend Pete in his country mansion.

A source said: "Kate can be like an ice maiden when she doesn't take to someone, and things between her and Agy have been very frosty. Everyone keeps making comparisons about them, and it is getting on both of their nerves.

"Kate is feeling particularly sensitive because Agyness is only just starting out and is nearly 10 years younger than her.

"She feels Agy is trying to copy her. She hangs out in similar places and they have friends in common.

"And she went mad when she heard Agy had become close mates with Pete. Kate had planned to nip into Pete's for his birthday party. But she heard Agy was there and said it would be too awkward.

"We're also concerned how Agy's relationship with Pete might affect her career. It only needs her to be in the wrong place at the wrong time with him and it could all come crashing down around her ears."
