The upcoming Aaliyah biopic will shed light on the star's alleged secret marriage to R&B singer R. Kelly when she was just 15, according to the film's producers.

Disney star Zendaya Coleman is to play the tragic star in a new Tv movie titled Aaliyah: Princess of R&B, and it has now emerged the project will detail the singer's controversial relationship with her music mentor Kelly.

The pair was alleged to have wed in secret in 1994, when Aaliyah was 15 and Kelly was 27, but it was never officially confirmed. A marriage certificate later surfaced, appearing to show Aaliyah's age falsely listed as 18, and her parents are rumoured to have had the illicit union annulled.

Executive producer Debra Martin Chase tells New York Post gossip column Page Six, "Aaliyah's personal and professional relationship with R. Kelly will be explored with care in the film as we set out to depict her life with the utmost respect. Above all else, it's our hope to inspire an entirely new generation with her music and larger-than-life talent."

The movie will cover the singer's life from the age of 10 right through until her death in a plane crash at the age of 22 in 2001.
