There's blood--and boobs--in the water!

The original 1978 horror flick Piranha featured cutie Janie Squire's breasts as fish food, but the 2010 release Piranha 3D is bigger in every way!

In addition to being shot in 3D, the new Piranha has porn star Riley Steele and gigantic-jugged Survival Island boobstress Kelly Brook wearing nothing but flippers and undulating together underwater.

You don't have to be a piranha to want a big mouthful of that.

Piranha 3D is out this Friday, August 20. Can't wait that long for Kelly Brook's bare breasts in glorious 3D? Members can see those heaving hooters in all their bare, beach-bound glory here.
