Paul McCartney and his wife, Nancy Shevell, escaped the cold this holiday season and are currently enjoying themselves in St. Barts. Shevell, 56, flaunted her toned bod in a green bikini while the two took a PDA-filled stroll along the beach on Sunday.
Check her out showing off her impressive abs during their romantic getaway.
Shevell -- who serves as vice president of her family's transportation conglomerate, which is reportedly worth nearly a half billion dollars -- married 73-year-old McCartney in October of 2011. The two have been dating since November 2007.
The brunette beauty is the legendary musician's third wife; McCartney's first wife, Linda Eastman, died of breast cancer in 1998, and he split from his second wife, model Heather Mills, in 2006 after four years of marriage.
