Stella McCartney is reportedly trying to find a new girlfriend for her father Paul McCartney because he’s lonely after his split from Heather Mills.

According to the Mail on Sunday, Stella introduced Paul to a friend of hers recently and they got along well.

A source told the newspaper: “He met this lady and liked her a lot, but he is totally paranoid about getting close to another woman. So it is hard to say whether anything is going to develop.”

The source added that Paul recently asked friends: “What is the point of all my money and success now?”

“Paul is incredibly lonely right now. He says he is only able to keep going because of [daughter] Beatrice and his music. They are the things that are holding him together.”

The source went on to reveal that Paul has been writing an open-ended letter to Beatrice about the breakdown of her parents marriage, setting some of it to music: “He is writing this down now so that, if she chooses to, she can read it when she is older. He wants her to understand what has happened from his point of view.”

“Paul never imagined he would have a child who would grow up in an environment like this, at the centre of a vicious divorce with an utterly divided mother and father. It has wrenched him in two.”

“He fears that Heather is saying inappropriate things to Bea about him, and loading her with thoughts against her father. He has some evidence of this.”

“He feels that because it was he who left Heather, and not the other way round, she can really load the situation against him in Bea’s mind and make him the reason it has all gone wrong. He is desperate that Bea understands what has been behind it. So it is very important to Paul that he gives Bea his side of the story; that she understands how it all went wrong and that he didn’t want her to suffer.”
