Jamie Hince has been spotted partying with a blonde.

The 46-year-old musician's marriage to Kate Moss is said to be on the rocks but he was seen hanging out with 29-year-old Victoria's Secret model Jessica Stam following one of his gigs in the United States.

A source told The Sun newspaper: ''Jamie was carefree and in great form. Jessica made straight for him and they appeared to be very close and friendly. The were very flirty with each other, very cuddly.

''She made sure they got close before she went home at the end of the night. Kate will be devastated to see Jamie moving on with a younger version of herself.''

After partying until two in the morning at the Kibitz Room bar in West Hollywood, the pair left separately, with Jamie being driven back to his hotel.

Meanwhile, a source previously claimed Jamie and Kate's marriage was ''properly over''.

They said: ''They are properly over as a married couple. It's gone past the point of no return. Jamie's just waiting for Kate to move forward with divorce proceedings.

''Neither are in any hurry but they both suspect there won't be a reconciliation. They accept they'll probably have to make some sort of statement but don't want to feel forced into anything.''
