MTV's 2007 VMA experiment - the show was broadcast live from Las Vegas and took place in various rooms of the Palms Hotel & Casino - was as energetic and unpredictable as audiences hoped for. Britney Spears performed at the top of the show in a widely-discussed comeback performance, sporting a sparkly bra and a large cast of sexy dancers. Performances from Kanye West, Justin Timberlake, Rihanna, and others peppered the brisk event, which breezed along with celebrity guest appearances, scathing jokes from Sarah Silverman, and liberal servings of MTV's winking coolness. Plus Pamela Anderson exes Tommy Lee and Kid Rock got in a minor brawl. What more could you want?The coveted moon men were handed out to Timberlake for 'Male Artist of the Year' and 'Quadruple Threat', Rihanna for 'Monster Single of the Year', and Fergie for 'Female Artist of the Year.' The Black Eyed Peas member and solo star was a no-show this year - she was busy fronting the Jerusalem Rocks Festival with the BEP boys.
