The way Justin Bieber's been behaving lately, it was only a matter of time until somebody asked the question: Does he need to go to rehab? According to RadarOnline, the 19-year-old's manager, Scooter Braun, wants him to seek treatment for his out-of-control partying, pot smoking and drinking.

"Justin is hanging out with the wrong people," a source close to the star tells Radar. "It's been one incident after another with him."

Justin's been in plenty of altercations in recent months – fighting with paparazzi and his own neighbors – and has been acting erratically (yesterday, he made the pilot of a private plane wait for 8 hours in Miami while he reportedly searched for his pet monkey).

And then there's the Instagram video he posted yesterday, shirtless and giggling, which led to speculation that he was high.

"Scooter wants him to go to rehab to get his act together," the source says. "Justin needs to get away from the bad influences in his life."

Radar reports that Scooter isn't the only one concerned. Justin's mom, Pattie Mallette, is also said to be worried.

"People who have known Justin for a long time see what's going on now, see the constant partying, and they think he's headed for big trouble."
