Twilight saga’s Kellan Lutz is the newest hunk to bare his muscles for Calvin Klein underwear. The huge red X on the ad signifies the Calvin Klein X Underwear range.

So what are Kellan’s thoughts on this sexy project?

The 24-year-old revealed to PEOPLE: “I started out modeling so this is the pinnacle. What more can you do than be on a billboard for something that you grew up thinking was super sexy and classy? It’s really prestigious and I love it.”

Was he nervous about being so unclothed for the shoot? He said: “With modelling, there are guys who do the Zoolander thing and it shows off as desperation.” He added: “You just have to have confidence, kick back and have fun with it.”

Though he will be on billboards everywhere, it is nice to know he is still modest: “I don’t see myself as perfect. I never will be and I never want to be. I’m not the good-looking guy with the nice hair like (Twilight co-star) Rob Pattinson. I enjoy being not so pretty.”

Can we all chime in and say: YUM! Do you think Kellan looks hot in these ads?
