It was the hottest show in town, and with good reason. Jay-Z, Chris Martin, and Kanye West headlined an all-star concert at the grand opening of The Cosmopolitan hotel in Las Vegas on New Year's Eve. Among the star-studded crowd -- which included Rihanna, Alex Rodriguez, Cameron Diaz, Mark Wahlberg, and Jennifer Lopez -- were Chris and Jay-Z's wives Gwyneth Paltrow and Beyonce Knowles. Not a bad turnout if you ask us! Kevin Mazur/WireImage.com - December 31, 2010
