and his wife Nancy were in a world of their own as they enjoyed a romantic beach day in St. Barts on Sunday.
The musician, 83, and his wife, 66, who are regular visitors to the Caribbean island, enjoyed a passionate kiss during a dip in the ocean.
Nancy couldn't keep her hands off her Beatles legend husband, pulling him in for hugs as they cooled down with a swim.
The American businesswoman was well protected from the sun in a brown, long sleeve swimsuit teamed with a wide-brimmed sun hat and shades.
Sir Paul donned a navy swim top and patterned shorts, beaming as he enjoyed the beach day with his wife of 15 years.
Paul and Nancy got married in 2011 after meeting in 2007 and both have children from previous relationships.

Nancy shares son Arlen with her ex-husband Bruce Blakeman, while Paul has Stella, James, Heather and Mary with late ex-wife Linda McCartney and daughter Beatrice McCartney, 19, with ex-wife Heather Mills, 55.
Paul coupled up with Nancy when the pair were on holiday in Morocco with his brother Mike and the musician serenaded her on the hotel's piano.
The star has detailed how they weren't yet officially a couple and were sleeping in separate bedrooms when he made his move.
Paul explained: 'The piano was sitting in the foyer all day long, and because the rain would not stop, I sometimes went and just noodled on the keys.'
'I was thinking all sorts of loving thoughts towards Nancy, and while I was at the piano, I could see that the waiters who were clearing up were listening.
'But it was nice and romantic, it was a perfect moment, and I thought to myself, we’re not going to stay in separate rooms tonight.'
Paul previously revealed his signature dance moves were responsible for his lasting romance with his wife.
Writing in his book, The Lyrics, Sir Paul, the Beatles star explained how he knew Nancy was a keeper when she matched his energy on the dancefloor.

Paul, who has previously married to Linda McCartney and Heather Mills, wrote: 'There’s no denying it, I really enjoy dancing.
'It’s something my wife Nancy and I are particularly keen on.
'After a show, when the band and crew get together for a drink, we’re always the first ones on the dancefloor. Certain songs will just get you dancing.'
The musician's latest project is the recently released Prime Video documentary, Paul McCartney Man On The Run.
The project follows Paul's extraordinary life following the breakup of The Beatles and his time as a solo artist and a part of his later band, Wings.
But as he reflected on his career in an interview with director Morgan Neville, Paul spoke about how he feels when he is criticised by people.
