Robert Pattinson in a G-string? It's true. The Twilight hunk revealed that he was forced to wear the revealing undergarment for his sex scene with Kristen Stewart in Breaking Dawn.

While some fans might think Robert Pattinson wearing a G-string is sexy, others find it hilarious to picture the smoking hot Brit in such an outfit. (Wonder what Kristen Stewart thought?) However, RPattz is a pro, and does what he has to do for his film roles. (That's dedication!)
"They [gave] me a big G-string, but it was too small for me. It was like old ham," Rob joked. (Gross!) Thankfully, Pattinson has never seemed uncomfortable doing his job. In fact, before hitting it big with Twilight, Rob portrayed gay artist, Salvador Dali, in the film Little Ashes, and had multiple love/kissing scenes with his male co-star.
It's a sign of a great actor when he's willing to give himself 100% to a role, and really make it his own. Robert Pattinson is earning a great reputation in Hollywood, and will hopefully be around for decades to come!
