Robert Pattinson graces the current cover of Playgirl UK, and since the Twilight hunk doesn't strip down for an interior spread, we have to wonder how his handsome face ended up on the front of the naughty mag!

We've contacted Rob's manager and legal rep about the cover, and it's not clear whether the actor approved of this image being used by Playgirl UK. If you remember correctly, Jessica Alba successfully sued Playboy back in 2006 for using her photo on the cover of their March issue without her permission, so we're wondering if something similar will come from this...

But fear not, Robsessed fans -- it sounds like we'll be seeing plenty of the actor's sexy butt in the upcoming film Bel Ami, which hits theaters later this year. Of the amount of naked screen time in the movie, Robert recently told MTV News, "I think there's quite a bit of nudity. I think there's a lot of my crack in it!"
