17. The Princess Dowry

Complete story — includes the ending

Blair thinks her stepfather may have found a potential loophole in her prenuptial agreement that would allow her to escape her marriage to Louis. CeCe Rhodes, before her death, arranged for a secret Irish-themed wake to take place at Van der Woodsen penthouse. Georgina Sparks decides to leave her post at Gossip Girl to her loyal but incompetent husband, Phil, and crash the wake to stir up more trouble. Chuck learns that Dan was the one who sent the video of him and Blair at her wedding ceremony and sends a blast to Gossip Girl. However, Phil inadvertently leaves Chuck's name in the blast. William Van der Woodsen ( William Baldwin ) returns to the Upper East Side for the wake, as he is the executor of CeCe's estate. Ivy Dickens is announced as CeCe's heir and it is revealed that CeCe was aware the whole time of Ivy's real identity. Ivy evicts both Lily and Rufus from the Van der Woodsen penthouse. Carol Rhodes also reveals the identity of Charlie's father as William Van der Woodsen. The real Charlie 'Lola' Rhodes continues her affair with Nate but has little interest in getting to know her family until Georgina suggests to her there may be another reason why her mother hid her from them. Blair's personal accountant, Estée, is in love with Louis, and she convinces Blair to agree to having her marriage annulled as long as she does not say a word to the media, including Gossip Girl. However, this is all a ruse perpetrated by Georgina herself, who sends a photo of Blair and Dan kissing to Gossip Girl and the Waldorfs are once again threatened with responsibility of paying the dowry and declaring bankruptcy. Blair tells Chuck that she will always love him but is not in love with him anymore. Georgina no longer wants to act as Gossip Girl after revealing to everyone that she has been filling in for the real Gossip Girl. She sends her computer to Serena and leaves for Monaco to help annul Blair's marriage, in exchange for a favor down the road. Blair tells Dan that he is the one who has her heart and they begin a relationship. Title reference: The 2001 film The Princess Diaries.
