Gossip Girl, Season 4

High society and low blows are back as Gossip Girl continues for its much-anticipated fourth season.

Meanwhile, Nate Archibald, fresh off his painful breakup with Serena, decided to take a page out of Chuck's playboy playbook just as Dan Humphrey discovered he was going to have to settle down and be a father . . . to Georgina Sparks' (recurring guest star Michelle Trachtenberg) baby! Season four opens with a radiant Serena and Blair enjoying their grand and romantic summer in Paris . . . until Chuck mysteriously arrives in town with a new girlfriend and a new identity.
