Blair will be busy preparing her first Waldorf Designs fashion show in the next episode of "Gossip Girl". She's looking for a new face for her clothing line and it looks like Sage nabs the job. Claiming that she'll make the event "very memorable," the daughter of Steven causes a scandal as she strips down to her bra and shorts on the runway.

Meanwhile, Serena discovers that befriending Sage is trickier than she thought, especially when she is forced to put her issues with Blair aside to make Sage happy. Nate publishes Dan's first serialized article, causing a stir and producing a serious threat.

Also in "Dirty Rotten Scandals", Chuck begins to look into the clue that Amira left behind, which may help uncover what Bart is hiding. The episode will air Monday, October 22 at 9/8c on The CW.

New photos from the set of the drama series hinted that Blair and Chuck would finally tie the knot. In the pictures, Leighton Meester and Ed Westwick are seen filming a kissing scene at what seems to be their characters' nuptials at Bethesda Terrace in Central Park before Ed's Chuck is escorted by a police officer.
