Ed Sheeran is busy cooking up "something special" for the fans, he says.

The English singer-songwriter teased a short video on Instagram Monday with the vague caption: "Was recording something special today."

In the clip, Sheeran is dressed in a black T-shirt and jeans with a semicircle of background singers, also dressed in black, behind him.

Together in what appears to be a church, they sing an acapella version of his song "Afterglow" as the sunlight shines through the stained-glass windows behind them.

While Sheeran didn't spill any other details about the project, the teaser comes on the heels of his new single, "Bad Habits," landing the number one spot on Billboard's Global 200 and Global Excl. U.S. charts.

"Bad Habits. One month at number one," read a message from the artist's official Twitter account, shared on July 23. "Thank you all for listening and supporting Ed's new single."

"Bad Habits" is the lead single of Sheeran's upcoming fifth studio album.

The title and the release date have yet to be announced.
