A new documentary is making the stunning claim that Whitney Houston was bisexual. "Whitney: Can I Be Me" alleges that the "Greatest Love of All" singer had an intense relationship with her personal assistant, Robyn Crawford. The documentary explores the behind-the-scenes drama of Houston's 1999 world tour during which her husband Bobby Brown and Crawford got into a brawl over the star. "Robyn was the one who was keeping her together," said writer Allison Samuels in the film.
