Heather Mills has reportedly told friends she thinks she might get back together with estranged husband Paul McCartney.

The previously warring pair have called a truce recently and been holidaying near each other in the Hamptons, New York. A few weeks ago, the couple were snapped happy and smiling at the hand over of their three year old daughter Beatrice - compared to earlier in the year when they had to have nannies make the change-over.

A source close to Heather told the Mail on Sunday: “Paul and Heather are definitely much friendlier now. They don’t have long conversations about divorce settlements anymore. They leave that to the lawyers to sort out.”

“The bond which has brought them back together is their little girl. In the heat of the moment, a lot of hurtful things were said and done, but one thing Paul can’t ignore is that Heather’s a fantastic mum and Bea completely adores her.”

“That has changed Paul’s thinking more than anything else.”

The source added that Paul has apologised for his behaviour during the marriage: “He went so far as to say that he would always love her, and how much he respected her strength and determination.”

“Heather was blown away. So much so that she told me: ‘I know it sounds incredible, but I think he wants me back.’”

“He definitely misses he. Bear in mind that they had a real bond. She was such a big character, whether you liked her or not, and they had a very passionate sex life.”

“When they split up, at first he was just furious, but after a few months he started to grieve for the relationship. It’s a bit like a bereavement. Paul has always had a strong woman in his life, and right now he’s missing that quite badly.”

But sources on Paul’s side insist that it’s less about a reunion and more about Paul wanted to “do the right thing” by Beatrice: “Paul now realises he acted petulantly and foolishly [when he stopped paying for Heather’s personal security], and that taking away the security put Bea at risk, too.”

“He feels genuine remorse about it and has distanced himself from the people who stupidly advised him to take that course of action.

“He wasn’t thinking straight at the time and was given bad advice. The situation has been addressed and things are different now.”

The source added that Paul’s older children - daughters Mary and Stella McCartney in particular - have also urged him to downplay the bitterness in the divorce case: “[Mary] told her dad in no uncertain terms that they were desperately worried about the effect a stressful legal battle could have on his health.”

“Make no mistake, the kids did absolutely despise Heather. For a long time they wouldn’t even use her real name - they called her Mrs Rochester, after the destructive wife in Jane Eyre who ended up being sent to a lunatic asylum. But now they are sick and tired of having the family name dragged through the mud and they’re determined the war must end.”
