Kate Upton showed off her bouncy chest on the set of The Other Woman in West Hampton, Long Island on Thursday.

The model – who turns 21 years old next Monday – could be seen leaping into the air as she shimmied away with actress Leslie Mann.

While Leslie didn’t have much trouble maintaining her modesty in a pink hooded top and floral trousers, Kate risked disaster.

The blonde almost spilled out of her top - which was obviously buttoned down to enhance the look of her chest - as she quite possibly had the help of a small trampoline beneath her.

The wardrobe choice enabled her yellow bra to be seen as she pranced about outdoors, fashioning an orange top to keep her arms warm and a tiny pair of shorts.

It looked like a scene where their characters had been consuming quite a bit of alcohol as wine and vodka bottles could be seen in shot.

An apt choice of music would have been House Of Pain’s classic party track Jump Around.
