Paul McCartney, 78, enjoys boat trip with wife Nancy, 61, in St. Barts

Sir Paul McCartney started the New Year off with a bang as he continues to enjoy his sun-soaked holiday to St Barts with his wife Nancy Shevell.The Beatles star, 78, made the most of the warm temperatures on the island as he went for a boat trip with his other half, 61, on Saturday. The iconic singer went shirtless for much of the day as he went swimming with Nancy, diving off the edge of the boat numerous times. The couple looked in good spirits as they laughed and frolicked in the water together while making the most of their holiday.Sporting a freshly grown beard, Paul was spotted doing the backstroke in the water before he was helped on board by boat staff members.   Nancy donned a navy long-sleeved swimsuit for the day as she joined her husband by going for a dive.The couple put safety first as they swam with flotation devices for some of their excursion while Paul also sported a pair of goggles.     The couple also spent some time relaxing on the boat, with Paul sporting a white printed jumper and navy shorts as he sat alongside Nancy.Nancy opted for a white jumper and a pair of sunglasses, adding to her look with a beige fedora hat.The pair, who appeared to be joined by some friends on the boat ride, also put safety first with face masks. Sir Paul released new album McCartney III in December, having written and recorded it during lockdown earlier this year. And in a recent BBC chat with actor Idris Elba, the crooner admitted he 'didn't realise' what he was creating when he did it.He said: '[In] lockdown everyone cleaned out their cupboards and did all the stuff they'd been meaning to get around to. So [making an album] was my equivalent.'I wasn't trying to make an album. So suddenly I had these 10 songs, I thought, What am I going to do with these?'It was just the 10 because I didn't know I was making an album.' Paul went on to explain why he named his album McCartney III.'I realised, because I played them myself, I'd done McCartney I and McCartney II in the same vein, that this would be McCartney III. So then it was like, ok, I see what I'm doing now.'During lockdown, Paul stayed in the countryside with his daughter Mary and her children.Of the experience, he went on: 'I was really lucky. I was locked down with my daughter Mary and her family, and then I was able to go to the studio to work, it was a very safe place. We were distanced, we were always being very careful. 'I was on holiday in the beginning of the year and then lockdown hit, Covid hit, so I came back and I was locked down in the country.'[It] was good as it meant I was hanging out with four of my grand-kids so suddenly that was great.'I was able to go in the studio. The government said you can go to work only if you can't work at home. So I don't have a home studio, my home studio is 20 minutes away.'So then I just started thinking, what about that song I had a few months ago that I never finished. So we pulled that out and I'd work on that'. Few places in the world
