We love it when our music and TV worlds collide. It reminds us of the glory days of SM:TV Live and Live & Kicking when celebs would be tossed together and you wouldn't know what was going to happen. So when Katy Perry was on Aussie radio show Kyle and Jackie O, they decided to surprise her with a phone-in from one of our and her favourite Australian comedians and characters. Yes, Katy Perry just meet Ja'mie King AKA Chris Lilley of Summer Heights High fame (via phone but still it's amazing).

Now Katy does prove that she's better at playing the part of a popstar than actually being one (see every live performance she's ever done for reasons why), and she's clearly up to speed on her Private School Girl as she ILYs and quiches with Ja'mie completely naturally. And Lilley has a great time trying to trip her up and calling her povo among other things.

All in all, it's brilliant. (Some NSFW language because Ja'mie has a mouth like a sailor)
