Things steaming up between Macca and his new girl Nancy Shevell

London, Apr 2 : Its looks like things have started steaming up between the latest couple making headlines- Sir Paul McCartney and his millionairess lover Nancy Shevell.

Shevell was spotted applying sun cream into McCartney's chest while holidaying at the Caribbean island of Antigua.

The 65-year-old ex-Beatle lounged on a boat as Nancy, 47, massaged the lotion front and back.

Then, he showed the New York millionairess how athletic he can be - with some leg exercises and a display of diving skills.

"They were showing lots of affection. She took care that he didn't burn in the sun, while he was handing her towels in the rain," The Sun quoted an onlooker, as saying.

"They seem in the honeymoon stage of the relationship," the onlooker added.

A guest at the resort where Macca has a 6,000 pounds-a-night villa, said: "People are thrilled."
