In the season finale, Chuck attempts to propose to Blair, but is interrupted by Dan, who reveals that Chuck had slept with Jenny. Two weeks later, Blair and Serena depart for Paris intending to spend the summer together.
Blair then teams up with Dan when the two share common goals. They also end up working together at W. magazine, where friction develops between the two.On Valentine's Day, she discovers that Chuck has romantic feelings for Raina Thorpe, the daughter of his business rival. Later, she and Dan spend the evening talking on their cell phones while watching Rosemary's Baby.Blair later quits W. and is shown asleep with Dan in his Brooklyn flat. Later, upon growing curious of their feelings for one another, Blair and Dan share a kiss before the mid-season hiatus.
Blair eventually decides that she wants to be with Chuck, but shuns him once again after he tries to humiliate Dan.She is later courted by a prince from Monaco named Louis. During a private confrontation, a drunken Chuck punches a window after he finds out Prince Louis has proposed to Blair, which cuts Blair's face as it shatters. Afterward, Blair chooses to accept a proposal from Louis. Blair later attempts to warn Chuck about potential trouble in his family. She is then abducted by an enemy of the Basses, Raina's father Russell Thorpe. Chuck later rescues Blair and apologizes for his violent actions. Following a night out together, the two have sex before Chuck advises Blair to return to Louis, believing that she will be happier with him. However, the season ends with the revelation that Blair may be pregnant.
Though she insists that she is in love with Louis, Blair begins to seek Chuck out as the season progresses. The two eventually declare their love for each other prior to a car accident. Though both recover, Blair suffers a miscarriage from the crash. At the wedding, Gossip Girl releases a recording of Blair confessing her love for Chuck. Nevertheless, Louis and Blair get married, though Louis informs her that they will have a loveless marriage of convenience. She then receives support from Dan, leading them to share a kiss on Valentine's Day. Amidst these developments, Blair grows conflicted between her feelings for Dan and Chuck. After taking steps to end her marriage, she chooses to begin a romantic relationship with Dan.
