With a sterling roster of rising stars that includes Selena Gomez, Demi Lovato, AnnaSophia Robb, the Rosso twins (Camilla and Rebecca), the Jonas Brothers, the Naked Brothers Band, Aly & AJ and Sara Paxton, Creative Artists’ Nick Styne reps some of the biggest under-21 talent in the business. But the proverbial dad doesn’t want to be known only as the go-to youth agent.

“I’m not just a kids guy,” he says, “but there is something amazing about it.”

Styne relishes the opportunity to introduce new talent to the world in the hopes that he’ll be able to represent them for decades to come. For example, he signed Cameron Diaz before “The Mask,” when she was just a plucky 21-year-old brand new to the biz (she even followed him from ICM to CAA when he switched agencies in 2003).

“I feel like we’ve grown up together,” the actress tells Variety. “When I first started looking at agents, I said to him, ‘Your bullshit is the most believeable.’ But then what I found out over the years was that it wasn’t bullshit.”

Styne remembers recently sitting down with Diaz, going over some old photos. They stopped at a picture of Diaz, Styne and her late father, Emilio Diaz, standing arm-in-arm at her first big movie premiere.

“We just looked at each other and realized, wow, we’ve been together for that long,” Styne recalls.

It’s exactly that sort of longevity Styne says he wants to maintain with his kids — a term he uses endearingly.

“When I look at these younger artists now, I want to be sitting there with them 15 to 20 years from now looking back and saying, ‘Oh my God, Selena, remember when we were dancing at your sweet 16?'”

Styne says he loves to grow with his clients, no matter what their ages when the partnership begins.

“We represent some of the most talented people in the world, and some of the most talented people in the world are children.”

Recent breakthrough: Demi Lovato and the Jonas Brothers hit it big with “Camp Rock.”

Role model: “My father.”

Up next: Lovato and the Jonases now have their own shows in the works: “Sonny With a Chance” and “J.O.N.A.S.”
