Whitney Houston‘s best friend, Robyn Crawford, writes in her upcoming memoir that she and the late singer had a physical relationship, which she says ended over worries about how it would affect Houston’s career. In her book, “A Song for You: My Life with Whitney Houston,” Crawford writes that their first kiss was “long and warm like honey.” “As we eased out of it, our eyes locked, my nerves shot up, and my heart beat furiously,” the book reads, according to an excerpt released by People on Wednesday. “Something was happening between us. We never talked labels, like lesbian or gay. We just lived our lives, and I hoped it could go on that way forever.” Crawford and Houston first met as teens in the summer of 1980 in New Jersey, where they were both counselors at a summer camp. Crawford said their physical relationship ended by 1982 after the singer’s career began to take off. Houston allegedly told her that it would make their “journey more difficult” and told Crawford “living that life meant we would go to hell.” The memoir comes out on Tuesday, Nov. 12.
