Justin Bieber pics: In swimtrunks, on the court for 'Shaq vs.'

justin-bieber-shaq-vs-02-320.jpg Justin Bieber is taking over your TV, one network at a time.

Before he makes his acting debut on CBS' "CSI" this fall, he's taking on Shaquille O'Neal on the season finale of "Shaq Vs.," airing Tuesday, Aug. 31 at 9 p.m ET on ABC.

We get an early look at what to expect, and it looks pretty fun so far.

We already know that O'Neal challenges Biebs to a dance-off. The two went head-to-head at Bieber's concert in Orlando, Fla. earlier this year.
