Nick Carter to AJ McLean — Mind If I Hit You in the Nuts with a Baseball Bat?

Breaking Balls
The Backstreet Boys are still a bunch of jackasses … just ask Nick Carter, who went Johnny Knoxville all over AJ McLean“s balls today … WITH A BASEBALL BAT … and it was all caught on tape.

The stunt took place during a photo shoot with celeb photographer Tyler Shields. We really have no other explanation for why this happened.

Now … here are a couple of our favorite BSB songs … Quit Playin” Games (With My Testicles), Ball I Have to Give, and Everybody (Backstreet”s Sack).

And we can”t forget our favorite album … Black & Blue … or is it Unbreakable Okay, we”re done.
