'Justin Bieber Needs An Intervention,' Says Addiction Specialist Candy Finnigan

Justin Bieber has left Intervention star Candy Finnigan enraged after the star posted an Instagram video last week of him mocking drug and alcohol addict Rocky Lockridge's cry.

Bieber can be seen wailing in the clip, before the camera then cuts to Finnigan's rehab session with Rocky on the TV screen.

The Baby superstar shared the video alongside the caption: "Funniest cry ..... Lol" (sic)

However, Candy definitely didn't see the funny side, according to TMZ, with the addiction specialist saying: "We can only pray that when, not if, Justin needs an intervention ... that someone as loving as Rocky's family will be there for him."

Uh-oh!

Meanwhile, Candy hasn't been the only star blasting Bieber recently, with Zach Galifianakis also taking a swipe at the star in the recently unveiled Funny Or Die interview.

The episode starts out with Galifianakis saying: "It's really exciting to talk to you, especially right in the middle of your public meltdown," before things quickly escalate, with Bieber not saying much when Zach quizzes him on recent events.

Other questions that the actor-turned-host fired at Biebs included: "I've just never interviewed a 7-year-old before. What was the last toy you got in a happy meal?", "Your young punk attitude is not going to work in this interview. You understand me, son?", "You've had three hairstyles, so what's next for your career?" and "You know what? I don't like your attitude, to be quite honest. You're too young to be smoking pot and pee-peeing in buckets and driving up and down the highway fast. I don't think your mom would really mind if a stranger whipped her son."
