Justin Bieber 'Between Two Ferns with Zach Galifianakis' VIDEO: 'Hangover' Star Spanks Selena Gomez's Ex with Belt in Hilarious 'Funny or Die' Clip

"Hangover" star Zach Galifianakis is back with another hilarious rendition of "Between Two Ferns" - this one featuring "Believe" crooner Justin Bieber. Let the awkward wisecracks begin!

Galifianakis kicks-off the interview by thanking the Biebs for being their since it's "right in the middle of his public meltdown." The comedian also finds it tough because he's "never interviewed a seven-year-old before." Ha. From the get-go, he let's Bieber know that his "young punk attitude won't work in this interview."

Galifianakis goes on to ask rather oddball questions, including: "Is it fun to be cocky?" and "You've had three hairstyles, what's next for your career?" and "When you're in the recording studio, do you ever think, 'Hey, what if I don't make something sh*tty?'"

The "Due Date" funnyman then discusses several "controversies" surrounding Selena Gomez's ex. His advice - "You're too young to be smoking pot, and pee-peeing in buckets, and driving up and down on the highway fast!" Galifianakis then takes off his belt and "spanks" Bieber with it.

All for good laughs! And it works - the Funny or Die video has since gone viral online. Check it out:

This is by-far the best Bieber interview yet. (Still, the Biebs' doesn't get to answer who he's currently dating!)
