While some think new judge Steven Tyler may be taking things too far on American Idol, the father of four and grandfather of one is harmless, and is actually saving the show, says daughter Mia Tyler.

"We're a very sarcastic family," Steven's model turned photographer daughter, Mia Tyler, explains to Life & Style. "He's the funniest man I know. He's saving the show because it was kind of boring before. There's only so many times you can watch Simon be mean to people."

While he's trying to be wild and controversial on-screen, he isn't all pheromone-soaked silk scarves and spandex off-camera. Indeed, after having completed rehab for heavy drug and alcohol use in 1986 and getting treatment in 2009 for a painkiller addiction, a sober Steven has settled into his own version of family life. "He's very much a dad when he's home," Mia tells Life & Style. "He's very protective and gets mad at us for not cleaning the catlitter box -- typical dad stuff."

"It's so nice to see him up there," says Mia. "He loves it!"
