Joe Jonas is the biggest flirt of the Jonas Brothers, Kevin Jonas revealed on the CBS' The Early Show Tuesday.
"He's a ladies' man," Kevin said while promoting the Bros' new 3D concert flick, out Feb. 27. "Girls love him!"
Joe is currently dating Camilla Belle, whom he met while shooting his "Lovebug" video. Before that, he dated Taylor Swift.
Nick also offered advice to the audience about wearing purity rings. The guys all wear the bands as symbols of their virginity.
"It's about doing your best every day," said Nick, who's been dating Selena Gomez. "It is tough sometimes, but you do your best."
"We saw Paul McCartney," Joe said. "We didn't know what to do!"
