paul mccartney and nancy shevellPaul McCartney is reportedly thinking of marrying girlfriend Nancy Shevell - less than three months after his divorce from Heather Mills was finalised.

The couple, who were first linked romantically last autumn, have spent the last week on a road trip along the historic Route 66 across the US and a source told the News of the World that the time they’ve spent together recently has convinced Paul he wants to be with her in the long term.

The source explained: “They’ve been with each other 24/7 - a perfect way to see if they’re suitable for marriage. Paul’s not about to rush into anything, but he’s happier than he’s been for years. They’ve got so much in common.

“Paul’s utterly enchanted with Nancy and he’s already rolling the idea of marriage around in his head. He adores everything about her. He thinks she’s ‘The One’.”

And his children from his previous marriage to Linda McCartney, who are said to have fought with Heather Mills, are said to approve of the relationship too: “He [asked daughter Stella McCartney], ‘What would you say if I asked Nancy to be the next Mrs McCartney?’ And she joked back, ‘At least she’s financially independent.’

“The whole family thinks Nancy’s great - a vast improvement on Paul’s last love interest.”

Nancy is vice president of her family’s transport company operating out of Elizabeth, New Jersey and is currently in the process of divorce her estranged husband, lawyer Bruce Blakeman but the source said that that split is far more amicable than the one between Paul and Heather: “Nancy and Bruce have been separated a long time but her relationship with Paul has spurred them on to finally dissolve the marriage.

“They’ve moved on with their lives and Bruce approves of Paul. It’s all amicable.”
