Amazon billionaire Jeff Bezos and his bikini-clad girlfriend Lauren Sanchez get steamy on mega-yacht in St Barts

Jeff Bezos, 57, and Lauren Sanchez, 51, enjoyed a boat day with some friends in St. Barts on Sunday. The pair were pictured kissing, hugging, and slinging their arms around one another. Sanchez wore three different outfits, including a black bikini and matching sarong, a white button-down and sarong, and white shorts with a crop top. Bezos wore a button-down with several buttons undone before taking it off and showing off his buff body in black swim trunks. The couple had previously had a yacht outing on Christmas Eve and were pictured hiking - and packing on the PDA - last week.
