Fashion-lovers, get ready to set your DVR on The CW for November 16th—Lady Gaga will be strutting her acting chops on Gossip Girl!

The episode, titled “The Last Days of Disco Stick,” features Blair (Leighton Meester) arranging a secret Gaga show. The popstar herself is set to perform her latest single, “Bad Romance” on the small screen.

Meester describes Gaga’s style as “very avant-garde and kind of gothic.” It’s certainly no surprise, considering her crimson costume with outer pastries (above) is reportedly 30 feet long!

Aside from having a vested interest in fashion, Gaga reveals that she had another reason for guest starring: “My little sister is the hugest Gossip Girl fan ever.”
