Supermodel Kate Moss is reportedly furious with Sienna Miller after she dumped boyfriend Rhys Ifans over the phone.

Rhys, who is one of Kate's oldest friends, is reportedly staying at her London home while he gets over the breakup.

A source told the Daily Express, "Rhys is probably Kates best male friend. In fact, shes as close to him as a sister and shes very protective of him because she knows his vulnerabilities... Kate is very loyal when it comes to her friends. She has taken Rhys in and told him he can stay at her place for as long as he wants.'

The insider added: 'Hes in a really bad way and shes really angry with Sienna, even though Kate knew she would never stay with Rhys.'

Miller reportedly dumped the Notting Hill star after he became jealous of her spending time with her ex Matthew Rhys on the set of her new film 'The Edge Of Love'.

However Sienna seems to have picked herself up quickly as she was spotted at the Coachella festival in California last month with none other than Sean Penn...
