Zach Galifianakis 'Spanks' Justin Bieber for Calling him 'Cocky'

Justin Bieber agreed to be a guest on Zach Galifianakis' Between Two Ferns but the singer did not expect to be 'spanked' by the comedian, according to Daily Mail.

The quirky interview between the pop superstar and the funny man began on a gentler note but soon grew tense with Zach getting more riled by the minute. Zach, 43, rips into Justin, 19, for everything from having an 'attitude,' making lousy music, 'smoking pot and pee-peeing in buckets,' being 'cocky' and making disparaging remarks about Anne Frank.

Unamused by Justin's monotone responses, Zach then does the unthinkable by unlatching his belt and going in to whip Justin's backside. Of course it was all staged and okay by Bieber, but the physical exertion displayed by the Hangover star was enough to settle those upset by the pop - or punk - star's antics.

Between Two Ferns is a comedy show on the video website Funny Or Die that is hosted by Zach, who conducts interviews with various celebrities between two potted palms. 'My guest today is Justin Beiber,' Zach begins the interview in his famously funny, understated way. 'It's really exciting to talk to you especially in the middle of your public meltdown.'

Zach goes on to throw one question after another at Justin such as 'what was the last toy you got in a Happy Meal,' 'is it fun to be cocky?' and 'you've had three hairstyles. What's next for your career?' 'You recently said that Anne Frank could be a Beamer oh, a Belieber,' Zach begins another hot topic. Justin replies: 'I went to Anne Frank Museum and they said she was into pop culture at the end of the two-hour visit and I said I wish she was a Belieber.'
