SEE VIDEO! Kellan Lutz's X-rated Calvin Klein ad

Watch the Twilight star strip down to his smalls for the new men’s underwear 'X' collection advert

Brace yourself ladies. We've got our hands on the new Calvin Klein Underwear advert, featuring Twilight's decidedly buff Kellan Lutz.

With everyone suffering from a post-Oscars hangover today, we thought - like us - you might be in need of a little pick-me-up.

Enter the new Calvin Klein Underwear advert...

While we brought you the stills and the behind-the-scenes vid not too long ago, this is the first release of the actual ad.

And, it's fair to say, it's pretty darn hot.

Featuring Kellan Lutz of Twilight fame, alongside his fellow models Mehcad Brooks, Fernando Verdasco and Hidetoshi Nakata, the advert features the strapping lads stripping down to their smalls and uttering bleeped-out expletives to the camera.

While we're not utterly convinced by the apparent profanities, it comes as little surprise considering Calvin Klein's notorious penchant for provocative marketing.

Don't say we never do anything for you, loyal readers...

Enjoy!
