Gossip Girl was back filming on location in NYC today, and Blake Lively didn't let the rain dampen her mood. Blake kept warm in a pair of sweat pants and rain boots; however, when the cameras started rolling she slipped into a pair of lime green stilettos and ditched her baggy pants in order to show off her famously long legs. The new season kicks off Sept. 26, and Buzz has a first look at Gossip Girl's season five promo. The cast heads to the West Coast for the opening episode full of sexy hookups, lies, and, of course, fantastic fashion. Blake spent a few weeks in LA filming for that episode, which gave her additional time to hang with boyfriend Leonardo Dicaprio. He's currently on location in Australia filming The Great Gatsby but that hasn't stopped the couple from seeing each other since Blake's reportedly already visited Leonardo in Sydney.
