Kristen Stewart and Robert Pattinson
Kristen Stewart says her boyfriend Robert Pattinson's sexiness is the "biggest joke in the world," according to Sugarscape.

The actress told Glamour magazine: "The first time Rob was named sexiest man in the world it was the biggest joke in the world."

“We never stopped taking the p*ss and neither did he."

The joke wasn't just on Pattinson. Stewart said that the "sexiness" of other hotties she's worked with, such as 'Twilight' co-star Taylor Lautner and Chris Hemsworth in 'Snow White and the Huntsman,' was also hilarious.

She explained: "Geez, now I sound like I'm generalizing about attractive men. But there's something a little vain about working out every single day. Whereas, they're the greatest guys and all kind of goofy. That's why it's so funny."
