Pitbull + Ke$ha

Here’s what you can expect from this glitzy blowout: radio-tailored bleeps and bloops, swagged-out shades, heaps of glitter, and hands-in-the-air, bottle-popping entertainment. Miami party-rapper Pitbull offers little more than bangers to soundtrack a sweaty club soiree, but the underrated Ke$ha alone is worth the price of admission. Despite her maddeningly ditzy veneer, the snotty star sparkles with joy, honesty and a deadly serious commitment to having fun.
