Kate Upton's boobs in near Great Escape

London: Kate Upton's boobs come perilously near to escaping in a new promo for a bikini chain.

The top-heavy model jiggled her bulging breasts into the camera while shouting 'It's a wrap' in the video for swimwear chain Beach Bunny.

According to the Sun.co.uk, the eye-popping move proved the strength of the bandeau - an important factor for bigger-breasted women like Kate.

Kate filmed the video while in Belize shooting a new campaign for the Beach Bunny Bronze Collection.

And she revealed her delight at being able to design a few of the designs herself.

She said: "It's been by far my favourite shoot so far, not just because of the beautiful location but because I was able to design part of the collection.
