The British supermodel is keen to spend time with Jefferson Hack over the festive season for the sake of their six-year-old daughter Lila Grace, but Jamie is said to be furious at her decision.

A source said: "Kate is a modern woman with modern values. As far as she's concerned, so long as her daughter Lila Grace is happy and surrounded by the people she loves, then she's happy too. "This means inviting both Lila's dad, Jefferson, and her boyfriend, Jamie to her Cotswolds home - no matter what the consequences."

Kate has also invited Jefferson's girlfriend Anouck Lepere to spend the day with them, and is determined to make it as special as possible for Lila.

The source added to Britain's Daily Mirror newspaper: "It may be a little awkward and there are bound to be squabbles, but Kate reckons as long as she acts as a buffer, all will be fine. "Jamie loves Lila and Kate and obviously wants to be with them on Christmas day. He is less keen on the ex hanging around."
