When you are a trio of hot blondes, it is hard to hide - especially fabulous figures like those belonging to Movie Stars Cameron Diaz, Leslie Mann, and Sports Illustrated cover girl, Kate Upton.

But that didn't stop Diaz, 40, Upton, 21, and Mann, 41, from trying to sneakily spy on their on-screen former lover with binoculars while filming The Other Woman in the Bahamas on Friday.

The scene is just the latest antic for the famous co-stars, who have clearly been enjoying working on the tropical Caribbean island - even when it means dashing across a pool deck or engulfing themselves in the local vegetation.

As the three actresses high-tailed it across the wooden floor, Sports Illustrated model Kate looked like she was at risk of falling out of her bikini as her famous cleavage spilled forward.

The curvaceous 21-year-old barely kept everything covered with a loose hooded top with ethnic tassels as her blonde hair flew wildly.
While her co-stars ran barefoot, Kate easily kept up the chase in gold sandals, with her binoculars firmly in her right hand.

Cameron and Leslie were dressed equally as casual - although at far less risk of a wardrobe malfunction - in bikinis, colorful beach cover-ups and sun hats.
Along with their crazed sprint, the active day of shooting saw them hiding in a bush being not-so-subtle spies, and attempting to sneak unnoticed across the busy pool.In one shot, the women simply collapsed into laughter on a large bed-size lounger, giggling wildly in the sun.

Mann was the first to sprawl on the huge orange mattress, but Diaz soon joined her, with Upton making a flying leap to collapse next to them on her stomach.

With all the silliness going on, the trio couldn't stop smiling even when the cameras were no longer rolling.

The stars have been doing some female bonding on set this summer as their roles have seen them dancing around in the grass in the Hamptons, dashing dressed up in Manhattan, and now frolicking in the Bahamas.In the film, Cameron teams up with her philandering boyfriend's wife (Leslie Mann) and the pair form an unlikely friendship as they plot to get revenge on the love rat who has been seeing a string of women as well as them.

The comedy is directed by Nick Cassavetes, who was behind the camera for The Notebook and My Sister's Keeper, and is slated for release on April 25 next year.

The film also stars Nicki Minaj and Taylor Kinney, and was written by Melissa Stark, with Miami Vice alum Don Johnson in final negotiations to play Diaz's father.
