Harry Styles to Release a Single on April 7

Harry Styles is teasing something big to come on April 7, and sources tell Billboard it's a single.

A mysterious television ad -- in which an instrumental track is heard as Styles walks through a cloud of smoke -- aired in the U.K. Saturday (March 25). At the end of the clip, the singer's eyes gaze into the camera, just before the date April 7 flashes on the screen.

News of the One Direction star signing a recording contract with Columbia Records was confirmed in June. The April 7 release would be Styles' debut solo single.

Check out the teaser below.
