Just over a year since their separation, Paul McCartney and Heather Mills have sparked rumours that they’re having second thoughts about their divorce.

The Sunday Mirror is reporting that the pair, along with their three year old daughter Beatrice, are planning to spend Paul’s 65th birthday together next week after weeks of improving relations.

An “impeccable McCartney source” told the newspaper the couple are no longer just communicating through their lawyers but speak regularly on the phone and in person where possible: “We are talking about a total and very quick transformation from a state of complete vitriol between the two of them to something much more amicable.”

“It is as though Paul has reached saturation point with all the bitterness, and Heather - aware of the battering her public image has taken - has decided to genuinely try to bury the hatchet. He has always said he still loved her and Heather has basically grown very tired of being public enemy number one… Paul has just had enough of all the spite.”

“Paul’s daughters and his staff have noticed [the new friendliness] and are quite surprised by the speed of it all. Paul is being cautious, though, about how things will play out from here. At the moment, he is not in a hurry for the divorce to go through, which is so different to a few months ago. And she is definitely happy with the way things are at the moment.”

“Up until the wife-beating story came out, he would always say that he still loved her and that she loved him. After that he became very businesslike, saying ‘we have to work thing out because of Beatrice’.”

“Now he is back to being more like when they first parted, remembering what he liked and loved about her, her spirit and determination. It’s still a long way off them getting back together, of course. But I would not put all my money on the divorce going through.”
