Gloria Vanderbilt Stuns Anderson Cooper With Revelation About Lesbian Relationship

"This is news to me! You didn't mention this in the book, Mom."

After writing a book together, Anderson Cooper may have felt like he knew all there was to know about his famous mother, Gloria Vanderbilt, but it turns there was one thing that still shocked the CNN anchor about his mom — her lesbian love affair!

While being interviewed by People’s Jess Cagle to promote their book, The Rainbow Comes and Goes, Cooper briefly discussed his coming out process, which prompted his mother to share some surprising news of her own.

“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 shared.

“What? Hello?” asked Cooper in shocked response. “This is news to me. You didn’t mention this in the book, Mom.”

“Cynthia, her name was, and she came once to visit my aunt in New York on holiday,” continued Vanderbilt, who revealed she was 13 at the time. “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,’ and this is before the thing I knew about my mother. I thought, ‘No, this is something that’s not really what I want.’ It was very brief.”

Her mother, Gloria Morgan Vanderbilt, was branded a lesbian during a 1932 custody trial, in an attempt to paint her as an unfit mother — something that made the young Vanderbilt wonder if she had “inherited” lesbianism.

“That was very difficult for me growing up to try to figure it out,” Vanderbilt revealed.

Cooper actually pointed to that story as a reason he was originally nervous to come out to his mother, fearful that it had tarnished her thinking towards the LGBT community.

But it looks like after Vanderbilt’s latest revelation, her son had nothing to worry about.
