Meg Ryan is still a hard-bodied bikini bombshell at nearly 50-years-old!
The blonde babe made a splash south of the border on Cinco de Mayo, hitting the tropical beaches of Cancun with her beau John Cougar Mellencamp and their families.
The adorable actress, who usually drenches her figure in unflattering, frumpy fashions, reminded the world that underneath it all, she still has a fat-free and fabulous figure.
Mellencamp and Ryan have been attached at the hip since late 2010, when the rocker separated with his supermodel wife of 20 years, Elaine.
