Did Pete Doherty do the dirty on Kate Moss in Italy?

Babyshambles singer took student back to his hotel room

Kate Moss is hopping mad because she believes fiancé Pete Doherty cheated on her two weeks ago with a South African model - but she doesn't know the half of it.

Eight months ago, after the pair had been window shopping for engagement rings in Italy, the Babyshambles singer invited a 21-year-old Italian medical student called Lara back to his hotel room in Rimini.

'From the moment we met, Pete made it clear he wanted sex,' Lara told pal Luca, reports The People.

'He never mentioned Kate at all despite the fact she'd been with him just hours earlier. It was like she never existed.

'Lara says it was Pete's suggestion to go back to the hotel and she got swept up in the excitement of it all.'

Hard to see the appeal of a pasty-faced, sweaty drug addict but Pete, 28, has charmed Kate, 33, for over two years.

They first got together in 2005 but it looks like it could finally be over between them.

Last week Kate kicked the singer out of house in St John's Wood home and she's now said to be heading for a Caribbean island with daughter Lila Grace to find some peace and get her life sorted out.
