Paul McCartney joins swimsuit-clad wife Nancy Shevell in St Barts

He recently showed just how much of a hopeless romantic he is, when he serenaded his wife, Nancy Shevell, onstage while performing at a party.

And Sir Paul McCartney, 77, was spotted enjoying more time with the glamorous 60-year-old on Sunday, soaking up the sun on the shores of Saint Barthélemy.

The legendary rocker was seen sprinting into the French Caribbean island’s clear azure waters, while his swimsuit-clad wife years strolled on Flamands Beach.

Nancy looked elegant and youthful as she meandered along the shoreline wearing black swimsuit, which she teamed with a patterned long-sleeved top.

With a wide-brimmed straw hat resting atop her glossy brown locks, the American businesswoman shielded her eyes with a pair of tinted sunglasses.

Meanwhile, Beatles icon Paul was dressed for an afternoon of activity, stepping out in a black long-sleeved top and a pair of red shorts.

Taking a dip: Paul was in his element as he enjoyed a low-key swim 

After his brief dip in the ocean, Paul went back onto dry land to meet his wife of 11 years, who handed him a large red towel to dry off.

The couple chatted as they made their way along the beach together before heading back to their luxury hotel.

Their outing comes several weeks after Paul serenaded his wife during a surprise performance at a party in New Jersey back in November.

Musician Paul delighted guests with a performance of the 1963 Beatles hit I Saw Her Standing There at the party, held at Hudson House in Jersey City for the New England Motor Freight (NEMF) company.

In a video captured by one of the guests, Paul threw of his jacket before breaking into a rendition of the classic tune, with Nancy and the guests singing along in unison.

Another video also showed Paul dancing with Nancy and the rest of the guests to the Beyoncé hit Crazy In Love.

The party in honour of NEMF’s staff was held at Hudson Hous.e, which is based at Port Liberte and overlooks the Hudson River and the Statue Of Liberty.

Nancy, who celebrated her 60th birthday last week, is an executive for NEMF which is owned by her family, and is believed to have hosted the bash. 

Paul and Nancy tied the knot on October 9, 2011, exchanging vows at London’s Old Marylebone Town Hall register office.

Glamorous Nancy is an heiress to a haulage fortune and is Sir Paul’s third wife after Linda McCartney died in 1998. He divorced second wife Heather Mills 10 years later, in 2008.
