What do you get when you put one of the world’s most famous musicians in the living room of one of their biggest fans?
This.
You get this:

Carrie Bickmore was the pawn in one of the most brilliant radio stunts of the year - it is only January,we know, but it's still good - after turning up to her home to discover a little 'party' was there.
A video posted to the Carrie and Tommy Show's Facebook page shows Bickmore's production team and co-host Tommy Little waiting for her in her home, predictably yelling "surprise!" as she walked in.
"Surprise what?! It's not my birthday," she said.
