Gloria Vanderbilt managed to shock son Anderson Cooper during a recent People interview. "I, myself, when I went to [Miss Porter's School in] Farmington, [Connecticut] I went through a brief so-called lesbian relationship with a girl in school," Vanderbilt said, to which a visibly surprised Cooper responded, "What? Hello. This is news to me. You didn't mention this in the book, Mom." Mother and son have written a memoir together, The Rainbow Comes and Goes, which is out April 5. They are also being featured in an HBO documentary out April 9, Nothing Left Unsaid.
Vanderbilt said she was 13 at the time of the brief romance: "Cynthia, her name was, and she came once to visit my aunt in New York on holiday. We had this sort of lesbian relationship and it felt so great. It felt so good and yet I thought, 'There's something about this.' ... I thought, 'No, this is something that's not really what I want.' It was very brief." She added that she believes "almost everybody goes through" something similar "at one point," but nowadays, "we realize there's no difference. Love is love."
