Justin Bieber on 'CSI': Goofing off with cadavers

Pictures of Justin Bieber's acting debut on "CSI" have been released.

In the episode, which premieres Thursday, Sept. 23 on CBS, Bieber plays teen Jason McCann, whose only brother puts Biebs in a sticky situation.

Above, we see what's essential to any "CSI" visit: hanging out with the cadavers.

We also see Bieber with the slate, perhaps getting into character or trying to remember his lines?

Finally, we see Biebs pose with series star Marg Helgenberger. We wonder if that means they have scenes together. Hmm ...
