Joel Madden draws the line at a naked Britney Spears.

Madden and his brother Benji stormed out of a radio show down under after the hosts showed him a photo of Mz. Brit with nothing on...well...down under.

He tweeted:

"Just walked out of a FOXfm interview in Melbourne not in the mood to be a clown.  Most of the time I can put up with idiot morning show hosts but not today. I guess I have finally found some Aussies I don't get on with." 

Mr. Nicole Richie later told the producer he was offended by the image because he was a father.

"I think I'm a pretty laid back dude but you guys are getting on my nerves."
