Robyn Crawford is clearing the air on her much talked-about relationship with deceased icon and best friend, Whitney Houston, in upcoming book, A Song for You: My Life With Whitney Houston.

According to a press release, Crawford will detail her time with the icon, beginning when they met as teenagers.

"With warmth, candor, and an impressive recall of detail, Robyn gives readers insight into Whitney’s life and career. She traces the years from when she and Whitney first met as teenagers in the 1980s to the recording of Whitney’s first album and the infinite success that followed. From countless sold-out world tours to her epic rendition of the US national anthem to the set of The Bodyguard, her tempestuous marriage, and the birth of her only child, Robyn was there."

It goes on, "Since Whitney’s death in 2012, that trusted and loyal friend, Robyn Crawford, has stayed out of the limelight and held the great joys, wild adventures, and hard truths of her life with Whitney close to her heart. In A Song for You, Robyn breaks her silence to share the moving and often complicated story of her life and relationship with Whitney.

"Deeply personal and heartfelt, A Song for You is the vital, honest, and previously untold story that provides an understanding of the complex life of Whitney Houston. Finally, the person who knew her best sets the record straight."

Houston's ex-husband Bobby Brown claimed the superstar was bisexual, telling US Weekly in 2016 that she and Crawford carried on a same-sex relationship for years behind closed doors. According to the New Edition singer, Houston was afraid to publicly embrace her sexuality due to judgement from her mother Cissy Houston and others.

A Song for You: My Life With Whitney Houston is set for a November 2019 release.
