Twin rockers Joel and Benji Madden fight all the time when they’re living in close quarters – spelling trouble for their relationships with best-friend duo Nicole Richie and Paris Hilton.

The brothers, who front rock band Good Charlotte, are constantly bickering and deliberately destroy each other’s possessions in an effort to get a reaction.

But they never take their arguments on stage with them because they have too much respect for their fans to ruin a gig.

Joel says, “We don’t always get on that well. We do fight sometimes. It’s normally over something stupid, but our pride will get in the way. The last time we got into a fight he (Benji) took my computer and smashed it. Eventually though we just laughed about it and couldn’t remember what we were fighting about.”
