Two bad ass Pop Singers get in a Bitch Brawl (someone's bangs got messed up too)

Nick and Aaron Carter came to blows at their home on Monday, the night before they announced their new E! reality show House of Carters at the Television Critics Association gathering in Los Angeles. Asked what caused the dustup, Nick, 26, told PEOPLE, "Eh, we're brothers, it happened." Aaron, 18, added, "Yeah, we're brothers, but this time ..." He then lifted his bangs to expose a bruise near his hairline, above his left eye. How did the fight start? "Aaron jumped me and I jumped him back," Nick said, revealing only that they'd been arguing "over a little misinterpretation."

Aaron's twin sister, Angel, told PEOPLE a House of Carters cameraman broke up the fight. The whole scuffle was caught on tape. "You'll see it on the show," said Aaron. House of Carters, which debuts in October, features all five siblings living together in L.A. and trying to work on their relationship away from their parents. Backstreet Boy Nick is meant to serve as the family role model.
