She is Nancy Shevell, 47 — the American he was spotted kissing last November.
Just two weeks after his bitter divorce battle with ex-porn star Heather Mills, 40, Macca and Nancy are at the exclusive resort of Jumby Bay, Antigua.
And a friend said: “It’s great. They are really happy together and are very close.
"It’s a blossoming friendship and Nancy really cheers him up.
“Paul deserves some happiness after everything he’s been through.”
The ex-Beatle and businesswoman Nancy, a breast cancer survivor, have been spotted laughing, joking and riding bikes.
