Kate MossThe course of love never did run smooth...

Especially, it seems, where Kate Moss is concerned.

The supermodel is rumoured to be a singleton once more.

A torrent of love-goss suggests that she's split from her man, Jamie Hince.

We've heard similar break-up chat in the past, but this time sources close to Kate say the split is for good.

"Kate thinks there is no going back this time and has told Jamie to keep away from her," a source close to the star told The Daily Mail.

"Although she has said that before, she has never appeared as hurt as this and the rows have never been this bad."

The news comes on the back of a wild night of partying for Kate after Vivienne Westwood's ReIn happier times with Jamie Hince d Label show at London Fashion Week.

Kate was pictured crying as she smoked alone outside the bash - and later was seen dancing with Amy Winehouse's pal Blake Wood at hip London nightspot Bungalow 8.

"Kate was in tears at Vivienne's show and told a number of close fashion industry friends that it was over," the insider added.

"Jamie told her he was fed up with her reluctance to stop partying and focus on normality. We have heard it all before but this time friends felt her attitude was very different.

"They just don't see eye-to-eye. When their relationship is good it's amazing but when it's bad it's a tragedy."

Strong stuff, you may think - but we must point out that there's been no official word from Kate or her publicist on the possible split.

So in the absence of being able to check her Facebook status, we'll stop short of saying Kate's back on the market quite yet.
