The Jonas Brothers aren't afraid of Justin Bieber's success.

The pop trio - siblings Joe, Kevin and Nick Jonas - aren't worried their fans might start supporting the 'Baby' hitmaker instead of them.

Kevin said: "I think there is room for everybody. We're not afraid of anything or worried about anything. We're just being who we are and making music that we love. We're proud of the guys that are following their dreams. As long as they're doing it for the right reasons, we'll totally support them."

The brothers have always had a lot of female fans, and their girl admirers were seemingly relieved earlier this year to learn that Joe, 21, had split from his singer-and-actress girlfriend Demi Lovato.

Although they are no longer dating, Joe insists they are close friends and still have a lot of fun together.

He said: "Me and Demi, we've known each other for a long time. We're very close friends. We've been friends for a long time.

"Some things work out, some things don't. That's just how it is. It's always fun working on screen and off stage with Demi. We have a lot of fun."
