Although the tribute to the late I Will Always Love You singer will take place the Awards ceremony on Sunday, it is not known if Houston Jr. will sing one of her mother's songs.

Houston’s death rocked the music world when she was found dead in a bath tub at the Beverly Hilton hotel in February, a day before the Grammy Awards.

A tribute was staged at the Grammys, and further celebrations in her honour have taken place at the BET Celebration of Gospel and the NAACP Image Awards.

Shortly after her death, Whitney's vocal coach and friend, Gary Catona, said her whole personality had been affected by the deterioration of her voice through smoking and drug abuse.

He said: "When someone is a singer at that level, their voice is so much of who the person is. She identified with her voice. It was not possible for Whitney to be affected very deeply, psychologically and emotionally, by the fact she couldn't sing properly anymore."

Elsewhere at the Billboard awards, Stevie Wonder will receive the Billboard Icon Award while Chris Brown, Usher, and Justin Bieber will perform live.
