Stick-thin supermodel Kate Moss is apparently ?beside herself? following Rhys Ifan?s split from Sienna Miller.

The supermodel ? who?s never really been bestest buddies with ?The Edge of Love? actress Sienna ? has been hanging about Rhys since the break-up in an effort to cheer him up.

A source revealed: “Kate seemed beside herself. Rhys spent a few nights with her just after the break-up but he seemed to be in denial. He kept saying he could fix it.

“Kate said she knew exactly what he was going through because she it was similar to when she split from Pete Doherty last year. Kate made a real effort with Sienna for Rhys’ sake and she is upset to see him so devastated.”

In the meantime, Sienna is getting sympathy from her ex-boyfriend Jude Law.

An insider said: “Jude called Sienna and said she shouldn’t worry about what everyone was saying. He told her to focus on how well things were going in Los Angeles, adding that only she and Rhys really knew what happened.”
