Watch Hanson "Shout It Out," Hear The Full Album Early
Hanson Brothers Rachel Been

He may be a member of the group that brought the lighthearted song "Mmm Bop" to the world, but, when it comes to making music, Isaac Hanson takes his profession very seriously.

"I have a hard time with musicians who act like p**cks," the eldest Hanson member said in an interview with WENN, before singling out fellow musicians Kings of Leon (who are also a group comprised of family members).

"The Kings of Leon guys are running some risks," Hanson said of the group who canceled the rest of their summer tour after lead singer Caleb Followill walked off stage during a Dallas performance. "They're irritating people; you can't do that too much. Eventually the bad boy image affects fans' willingness to show up. Their fans will get bummed out."

Hanson went on to address the rumors of turmoil within the group, saying, "Everybody has their demons, everyone has their challenges. I'm a bit of a hothead in certain circumstances, but you gotta temper it because your fans are there and they've paid good money to see a show, and you gotta bring it. I don't wash my dirty laundry in public, I do my dirty laundry backstage I have flipped the bird at a few people that deserved it and told them to go f' themselves."

Hanson also compared Kings of Leon with Oasis, another band of brothers that imploded. "They got that too and it hurt them ultimately, because it made it hard for people to have a lot of fun at their shows -- because they were worried that Noel (Gallagher) was gonna get p*ssed off (and walk off)… But I don't think that they (Oasis) necessarily didn't finish shows."

Kings of Leon have yet to respond to Hanson's statements.
