Fitzy and Justin Bieber nearly came to blows at Coachella

Getting knocked over by an out-of-control headbanger isn't the only potential hazard of going to an AC/DC show…not when Justin Bieber is in the house.

Nova FM breakfast host Ryan "Fitzy" Fitzgerald nearly got into a fight with the 21-year-old at Coachella while heading backstage to watch AC/DC perform.

Wait, Justin is an AC/DC fan?

Fitzy relives the altercation in the video above. You've got to hear his description of Biebs – it's priceless.

Justin's apology tour appears to be officially over, as he's been making a general nuisance of himself at Coachella. The singer was reportedly put in a chokehold and ejected from Drake's performance area after getting into a scuffle with security on Sunday night.

It looks like the pint-sized pop star still has a thing or two to learn about playing nice.
