Justin Bieber's Dad Reveals Star May Soon Cut His Famous Mop Top

INSIDE EDITION's Megan Alexander asks Jeremy Bieber about one of son Justin's most defining characteristics: his hair!

Justin Bieber's voice has taken him to the top of the charts, but his hairstyle has made him a teen idol.

"He's always had kind of funky hair; I used to give him Mohawks," said Justin's dad, Jeremy.

Jeremy Bieber gets a kick out of all the fuss over the Bieber 'do. The Today shows Natalie Morales wore a Justin Bieber wig for Halloween and football star Tom Brady is sporting a real Bieber 'do!

But Justin's hair may soon be getting cut.

"I know he's talking about cutting it though," Jeremy revealed to INSIDE EDITION's Megan Alexander.

"What do you say to that?" she asked.

"It's up to him!"

At age 16, Justin is already an international megastar. But so many young stars like Lindsay Lohan and Demi Lovato have crumbled under the pressure...can Justin handle it?

"Are you concerned that Justin may burn out or become exhausted?" Alexander asked.

Jeremy said, "Justin is one of a kind. He's got a lot of energy, he loves what he's doing. I don't think he's going to burn out anytime soon, if at all. I think he's going to have a long future."

Jeremy says he tells Justin to "just be yourself and be good to people" to stay grounded.

When asked about Justin's social life, Jeremy says, "He goes on dates with girls periodically, he goes to the movies or whatever – he doesn't have a lot of time for a long-term relationship or anything."
