JUSTIN BIEBER and his team are hoping to score a more "adult" hit to help Justin transition from a teen pop star to "young adulthood."

--Supposedly, they want to do something like "Cry Me a River", which JUSTIN TIMBERLAKE had on his debut solo album, "Justified". (--It was the second single, and it got Justin a Grammy for Best Male Pop Vocal Performance.)

--A songwriter / producer named Sean Garrett has the task of creating it.

--He says, quote, "What we're trying to do with Justin is to segue him into young adulthood. The one great thing about Justin Bieber is the fact that his fans are going to grow with him.

--"So we want all the fans that started out with him to still be intrigued and excited about him, but we want to also stretch out a little bit and make the fans that are 22-23 years old love Justin as well."

--Meanwhile, here's video of Justin RESISTING a transition into "young adulthood." Apparently, Justin's manager told him he couldn't buy a toy helicopter, so he called his mom to ask for her permission. It's about a year old. Here's the link.
