Justin Bieber (sort of) covered Katy Perry’s hit track Teenage Dream at a recent gig.

It was during the soundcheck before a gig when Justin came out to chat to the crowd and answer their questions. Justin started the crowd singing the track before having a go. Then, when the Katy Perry track was played, Justin jumped onto the drums to drum along.

He then went on to big-up Xbox Kinect – which he thinks is even better than the Wii. We wonder if that helped their sales at all?
