Gossip Girl TV Series: The Complete Sixth Final Season. Six years after the first blast, Gossip Girl continues for an unforgettable final season. As season six opens, Serena is completely off the grid. Her friends fear the worst but hope for the best … yet even they can’t imagine where they’ll find her. Blair has offered Chuck her heart, but is it enough to help win back his empire? Dan has written a new book that promises to make more trouble than the first, and this time he has no desire to be anonymous, and Nate is determined to reveal Gossip Girl’s true identity, thereby making a name for The Spectator — and himself. Plus, Lily and Rufus turn on one another when Rufus makes a surprising new ally. And when Bart Bass, Jack Bass and Georgina Sparks show up to raise hell, it’s a fight to the spectacular series finale. Anywhere else it would be too much drama to handle, but this is the Upper East Side! So who comes out on top? That’s one secret I’ll never tell…. XOXO, Gossip Girl.
