Bieber's DJ to spin discs but will Justin show up?

IT'S Justin Bieber's party and he can do what he wants - including sending his own DJ in his spot.
Mine at Mansions on Pulteney St is holding a Justin Bieber party tonight and we hear Biebs' DJ Tay James is playing.
But the teen pop star, right, who's touring Australia and is playing at the Adelaide Entertainment Centre tonight, won't be making an appearance.
Which is probably the right way to go as an underage Justin would have to wear a wristband so he's not served alcohol.
