Hollywood's young A-listers were out on the town last night to attend the 2010 MTV Movie Awards in L.A. On the red carpet, the glitz factor was at peak levels as the likes of Kristen Stewart, Sandra Bullock, and Scarlett Johansson strolled past. Katy Perry had folks talking (yet again) by donning a bright blue wig and Zuhair Murad nude minidress which super sparkled in silver sequins. Unfortunately the look wasn't a winner, and all-too closely resembled what Lindsay Lohan chose to wear - a crystal embellished plunging jumpsuit by Pamella Roland. Making another dramatic entrance was Christina Aguilera, whose stunning Atelier Versace gown will no doubt help her on the comeback trail. The heavy chain detailing and shiny shredded asymmetrical black skirt ensured her ensemble was a standout in the style stakes.
