Lena Dunham joined Sia on stage as she performed her hit “Chandelier” on Late Night with Seth Meyers.

Lena Dunham Performs With Sia

Sia was booked as the musical guest on Monday night’s Late Night show, and she teased early in the day that her performance would welcome an “extremely special guest.”

Before the show, Late Night with Seth Meyers announced on Twitter that Dunham was the special guest, teasing followers with a photo of Dunham in costume.

Sia spent most of the performance laying down on a bunk bed while Dunham lip-synced around the stage. Wearing a blond wig and white button-down pajamas, Dunham twirled around the set, decorated as a bedroom. Props used in the odd dance include a role of toilet paper and cardboard cutouts.

Towards the end of the performance, Sia’s legs joined Dunham in dance and the two women cuddled up on the bed together.

This isn’t the first time Sia has enlisted a celebrity to take the stage in her place during a performance, as she prefers not to put herself on display. In May, Sia recreated the music video for “Chandelier” with the help of Dance Moms star Maddie Ziegler, 11.

Sia’s upcoming album 1000 Forms of Fear will be released July 8.
