In his upcoming movie ‘The Paperboy’ Zac Efron strips down to his underwear for a scene.  His butt looks really good, but we’d like to get better footage of his front.  Hopefully we’ll have more from this underwear scene once the movie comes out.

Rob Kardashian does thing on the reality TV show ‘Keeping Up With The Kardashians’, but occasionally likes to do some modeling work.  It looks like when he was modeling these underwear he couldn’t help himself from popping a boner.

Last week the pilot episode of ‘Persons Unknown’ aired and we got to see Jason Wiles exposed.  He stripped down and gave us a lot more than we bargained for…Look at that bulge!  We suggest tuning in this Monday for the first episode, should be a great show and maybe we’ll see some more male celebrity skin.

Alan Ritchson has a great ass and in that jock strap it looks even better.  He seems to be doing a lot more acting and less underwear modeling these days.  Luckily though, he starred in the movie ‘Blue Mountain State’ and was wearing a jock strap as well, exposing his bulge.

True Blood’s Ryan Kwanten displays yet another reason why vampires are so hot. Robert Pattinson is cute, but he’s got a few trips to the gym coming before he can match Kwanten’s body.

Jason Mraz

Jason Mraz has a  killer voice, but even a killer body, especially shirtless and in underwear. The crooner released his third studio album, We Sing. We Dance. We Steal Things. on May 13, 2008. The album debuted at number three on the Billboard Hot 200 giving Mraz his highest charting album was Mraz’s international breakthrough. Following the success of lead single, I’m Yours, the album broke into the top ten of many international music charts and charted in the top three in Australia and the US.

In answer to the age-old question, he obviously prefers briefs. See his nude pictures here.

Djimon Hounsou in Underwear

Djimoun Hounsou is definitely one of the hottest black celebrities out there. You might remember him from Blood Diamond with Leo DiCaprio and this year’s Push. He’ll be in a new movie called The Tempest later this year. You can see Djimon Hounsou nude here.
