Sir Paul McCartney has gushed about his new girlfriend NANCY SHEVELL - insisting he is "so happy".
The former Beatles legend stepped out with Shevell in London for the first time on Tuesday (16Sep08) to attend a charity event.
And MCCartney insists their recent trip to the U.S has cemented their relationship.
He says, "We had a brilliant time in the U.S. We stayed mainly in hotels but did the whole Route 66 gig.
"It was great and we're so happy."
MCCartney has been dating the American heiress since last year (07).
