It's the last of our On Tour With Greyson Chance episodes (tear!), but don't worry, guys. We're ending the series with a major bang. And by bang we mean the hottest Australian ever, Cody Simpson. And you thought the cameo by Miranda Cosgrove was good, eh?! You'll def want to watch this vid, where Greyson and Cody perform a super sick duet, not to mention shower two very lucky ladies with a gorgeous bouquet of flowers. Hey, guys, we like roses, FYI.
