When the director told her to ‘bust a move’ she obviously took the instruction quite literally.
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.

NEW KATE UPTON DANCE. It's a party to get involved with...

Under-wired underwear: A sturdy yellow bra held her breasts in as she pranced about

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.

Smooth moves: Kate is no stranger to expressing herself through dance

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.
But perhaps Kate was also teaching her co-star how to perform the Dougie dance which helped shoot her to fame.

The clip amassed almost 750,000 views in the first 24 hours.
