David Cassidy to Zac Efron: "Stay Grounded"

David Cassidy — ‘member him, from “The Partridge Family“? — has a few words of advice for Zac Efron: Keep it real.

“All I can say to Zac is that as long as he does good work, doesn’t lose his mind, and stays grounded as a human being, he’ll be fine,” Cassidy, 58, tells Britain’s Daily Mail as he’s about to embark on a U.K. concert tour (!).

He adds: “But he’d better fasten his seatbelt because it’s going to be a very bumpy ride.”

More after the jump…

Seems like Cassidy knows a thing or two about keeping it real. He says the secret to longevity in show business isn’t about having an adoring public. Rather, it’s about the talent, “and never about how many fans or photographers you’ve got outside your home.”

Yeah, I think that would mess with a person’s psyche big-time — worrying about the fans (or lack thereof) all the time. Go, David! And go, Zac!
