Gorgeous pop stars and famous actors arrived in NYC yesterday to attend MTV's Upfronts at the Nokia Theatre in Times Square. Although we're only interested in the celebrity action seen through our lenses, Splash had better give you the low down on what exactly MTV were up to.  Press reports have summed Upfront as a "focus on multiplatform opportunities across all of MTV's on-air and online properties, including MTV, VH1, Comedy Central, TV Land, Spike and CMT."
