Now that Terrell Owens has been claimed, Shaquille O''Neal is undisputedly the biggest name remaining on the free-agent market of washed-up future hall-of-famers in any professional sport.

So, with some time on his hands, the Big Aristotle made his way down to one of his old team's cities, Phoenix, where a certain teen pop sensation was performing a concert.

Not being one to back away from a once in a lifetime opportunity, Shaq made his way to the soundcheck before the concert and got a chance to show Justin Bieber his vocal skills.

Watch Shaq sing on TheSportingRave.com.

I won't be the one to judge the big fella's talent, but I was able to surmise the following from the minute-long video: Shaq loves Justin Bieber just as much as any pre-teen girl in America.
