Heather MillsPaul McCartney has instructed his lawyers to start divorce proceedings for him against his wife, Heather Mills, citing “unreasonable behaviour” and claiming she was “argumentative” and “rude to staff”.

But, according to the Mirror, Heather is shocked that he started the proceedings now - because she wanted to get in first.

A source close to Heather told the newspaper: “she wanted to divorce him…she didn’t expect it to happen this quickly”.

The couple had been reportedly arguing over the wording of the divorce settlement, usually an easy part of the procedure.

The source added: “she’s not going to make it easy. This could drag on.”

Heather reportedly turned down an offer of a “quickee divorce” recently.
