Abby and Ilana took to Spike's aptly named Lip Sync Battle to duke it out and determine who's the best at faking it. And even though Ilana's rendition of "It's Raining Men" was quite the vivacious belter (complete with back-up dancers), there's nothing quite like Abby's rump-a-slam-dunk "Humpty Dance." No wonder it's one of Ms. Glazer's "sexy songs."
Watch the madness below.
