Kate Upton Goes Topless For GQ Photo Shoot

Talk about racks on racks.

Though the teen model wishes she had smaller boobs, she had no problem gallivanting topless on in a new behind-the-scenes video from her GQ photo shoot posted on TMZ. The clip shows photographer Terry Richardson clicking away at Upton in teeny bikinis, where for the most part, she just keeps her bottoms on.

Fellas, don't watch this at work.
