Hot Granny Alert! Robin Wright And Naomi Watts Strip Down To Tiny Bikinis For New Movie

By Alexis Tereszcuk - RadarOnline.com Senior Reporter

These aren’t your regular, run of the mill grandmas!

But, in fairness, they’re not really grandmothers, they’re just playing them in a movie -- showing off bodies most grandchildren, let alone grandmothers would envy -- blonde bombshells Robin Wright and Naomi Watts stripped down to tiny bikinis Thursday and RadarOnline.com has the pictures of their sultry wet look.

Robin, 45, and Noami, 43, frolicked in the waves in Australia while filming their new movie The Grandmothers and neither of them looked in the least bit ready to collect their pensions yet.

Sporting a black bikini, Robin showed off a rocking solid beach body that would be the envy of any 18-year-old.

Meanwhile, Naomi poured her ample assets into a smoking hot purple bikini, soaking up the rays and splashing in the water for the shoot.

Both women have two children in real life but neither shows any traces of ever being pregnant, with their abs shining and their toned legs giving them the most enviable bodies on the beach.

The movie, based on the book by Doris Lessing, tells the story of two childhood friends who grow up and become infatuated with each other’s sons.

The lucky guys who get to play the love interests of Robin and Naomi are Xavier Samuel and James Frecheville and they were pictured horsing around with the sizzling hot cougars in the waves.
