Earlier this week she covered up in a one piece as she frolicked in the sea with her partner Liev Schreiber in the sea.
But Naomi Watts was a little more daring yesterday, stripped off to a purple string bikini.
The 43-year-old showed off her incredibly toned midriff and thin legs as she joined Liev and her two boys, Sasha, four, and Samuel Kai, three, in the Barbados waters.
The blonde added a pair of aviator-style glasses to keep her peepers safe in the sun.
When she hopped out of the water she covered up in a white, long-sleeved top and hat.
Liev donned blue swimming trunks and was spotted doing a hilarious dance, no doubt to keep the children entertained.
Earlier this week, Naomi donned a more modest blue swimsuit.
And it seemed to have the desired effect on her Scream actor partner, who could not resist grabbing her to plant a kiss on her lips as they splashed around in the ocean waves.The couple have been together since 2005, but it does not seem like their passion has waned over the years.
Naomi is enjoying a little down time after recently wrapping up work on her latest movie The Grandmothers in New South Wales, Australia.
The film - which is based on the novel written by Doris Lessing - tells the tale of two childhood friends and neighbours who fall for each other's sons.
It's just one of a slate of films Watts has in the works, including a biopic about Princess Diana.
The Oscar-nominated star is confirmed to be appearing in Caught In Flight about the final two years of Diana's life.
Diana's romance with the late Dodi Fayed will be featured in the film as well as her role in campaigning against landmines.
When it was announced in February that Watts had been given the role, she said: 'It is such an honour to be able to play this iconic role - Princess Diana was loved across the world, and I look forward to rising to the challenge of playing her on screen.'
