Only three beauties have made it to the finale. The judges pair the contestants with a real-life celebrity who parties with them all night, but, instead of getting to crash back at the hotel after a long night, the exhausted contestants are whisked to a new location to shoot a commercial for Las Vegas, and they must memorize lines, learn blocking and be at their absolute best. One completely cracks from lack of sleep. And, in a stunning game-changing moment, Vanessa Minnillo confronts the contestants and shows them exactly what the "spy" cameras have captured when the contestants were unaware. Who epitomizes both inner and outer beauty? Who will be crowned the winner, getting $100,000 and a photo featured in People magazine? Find out in the season finale.
