All week long we’ve been treated to some very entertaining photos from the new Calvin Klein Underwear ad campaign featuring Kellan Lutz, Mechad Brooks, Fernando Verdasco and Hidetoshi Nakata and just today, we saw a few HOT behind-the-scenes photos from the shoot. But I’ve since come across a behind-the-scenes video of Kellan Lutz on the CK Underwear photoshoot set and, let me tell you, it is HOT HOT HOT:

I honestly don’t think any y’all will mind taking another look at Kellan in his Calvin Klein undies … especially since this time, we can see him in motion. Hang on to your hats, folks, and check out this HOOOOOOOOOOT video after the jump …

SWEET BABY JEBUS!! This is a crazy-hot video. OY!! I just had to share this as soon as possible, I mean … right? “Mark Your Spot”, indeed! Enjoy!!
