Sources close to 33-year-old Kate, said that Sunday's engagement isn't formal but it's Kate's way of showing her love for Jamie - who she has been dating for a few weeks - and also her way of letting former love, rocker Pete Doherty, know that it is over between them - for ever.

Later Kate reportedly had a row with Rhys over the phone after she, Jamie, Sadie and pals went off to a party - but banned Sienna.

A source told The Mirror: "Kate made it clear Sienna was not welcome in the Primrose Hill clan and never would be.

The four bottles of vodka and crate of champagne at the party may have helped bring Kate's temper to the boil.

Meanwhile, it has emerged that twelve months after the cocaine scandal that rocked Kate's career, she has been axed from seven high-profile modelling contracts.

Kate has been dropped from a number of her most lucrative deals including those with Agent Provocateur and Coco Chanel.
