FUNNY: Zach Galifianakis Spanks Justin Bieber on ‘Between Two Ferns’ (PHOTO and VIDEO)

19-year-old Justin Bieber decided to stop at Funny Or Die for an interview with the "Hangover" star Zach Galifianakis for his "Between Two Ferns." But the teen star had no idea what's in store for him. For Bieber, the interview turned out to be humiliation and assault mixed with humour which Galifianakis is famous for.

The interview showed Galifianakis asking weird and awkward questions with snide remarks from Bieber. What started out as a normal interview, soon became violent with Galifianakis whipping out his belt for some real spanking at Beiber's cost.

Galifianakis started the interview by telling the guest, "It's really exciting to talk to you, especially in the middle of your public meltdown." Bieber looked stunned but continued to answer the questions.

The "Hangover" star continues to poke him by addressing him as a 7-year-old kid.

"I've just never interviewed a seven-year-old before so ... What was the last toy you got in a Happy Meal?" Galifianakis asked Bieber. "Baby" singer clarified that he is not a Happy Meal fan.

Galifianakis continued to bombard Bieber with ridiculous questions like "When you're in the recording studio, do you ever think 'Hey, what if I don't make something sh**ty?'" and "You've had three hairstyles. What's next for your career?"

The interviewer also asked Bieber about his controversial comment on Anne Frank being a Belieber if she would have been alive.

"Did you mean that if the Nazis hadn't taken her, and she'd lived to be in her 80s, she would've liked your music, presumably due to loss of hearing?" Galifianakis asked.

"Or, I think you were talking about time travel, and you think, if you could build a machine and go back to visit Anne Frank, she would've been a Belieber then," he continued.

The interview took a violent turn when Galifianakis brought the topic of urinating into a bucket and smoking pot.

"You know what? I don't like your attitude to be quite honest," Galifianakis declared.

"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 beat her son."

He got angry and whipped out his belt only to spank Bieber not one but three times.

Check out the hilarious interview.
