According to the Jonas Brothers, there's only room for one JB on the block. Nick Jonas dished to J-14 that he and his famous brothers have a nickname for the other JB, Justin Bieber.

"Bustin Jieber -- that's what we call him!" Nick told us. But is it because they're jealous of him? No way! "Justin's a good person," Nick spills. "I've met him a couple times. He's a really nice person!"

Should we start calling the Jonas Brothers the Bonas Jrothers? ;-)

Do you like the JoBros' nickname for Justin?
