Aly Michalka and Ashley Tisdale put on the ultimate cheer on the set of Hellcats, flashing their hot spirit squad bodies, not the least of which was Aly Michalka putting on a bare-midriff ab display just three degrees north of super sextastic. Looking at these cheercats can't help but remind me of long afternoons spent cramped up in a little HVAC duct above the high school girls locker room just waiting for cheer practice to end and shower time to begin. Of course, that was just a week ago, so the memories are still sharp. Cheerleaders are the most addictive kind of recreational drug. Enjoy.
