Finally, a long-awaited solo deal for the One Direction star has been signed, say sources.

Harry Styles has signed a recording contract with Columbia Records, the same label behind his group One Direction, Billboard has learned. Deal terms are not yet known and there is no timeline for a solo album, say sources.

The first hints of a Styles solo career came last year, when four songs performed and written by the star were registered with the American Society of Composers, Authors and Publishers (ASCAP).

Styles is currently filming the Christopher Nolan World War II drama, Dunkirk.
