“Extra’s” Renee Bargh sat down with Katy Perry, Lionel Richie and Luke Bryan ahead of the “American Idol” premiere!

Luke and Katy have dubbed Lionel “Dad,” but what’s the story behind the nickname? Katy explained, “We are just so rambunctious.”

She added, “Lionel is such a living legend and he has all these stories and he’ll be telling it… Then Luke and I are blowing up a whoopi cushion and putting it on his seat.”

“American Idol” premieres on Sunday on ABC.
