Osama Bin Laden once had the hots for Whitney Houston, according to one of the Al Qaeda leader's former sex slaves. Sudanese writer KOLA BOOF, 37, claims she was intimate with Bin Laden years before he masterminded the 9/11 terrorist attacks, and in her autobiography, DIARY OF A LOST GIRL, she claims the world's most wanted man fantasised about pop star Houston. In her book, Boof alleges Bin Laden joked about killing Houston's husband Bobby Brown and then inviting the HOW WILL I KNOW singer to join his harem. She says, "He had a paramount desire for Whitney Houston. "He mentioned her constantly, how beautiful she is, what a nice smile, how truly Islamic she is, but just brainwashed by American culture and her husband."
