In an interview with The Daily Beast published on Friday, the Real Housewives of New York City star alleged that she was groped by Simmons in an elevator years ago.
"He grabbed my a** in an elevator, he was just a pig,” de Lesseps claimed. “I haven’t told anybody about that before. I was grossed out. I was like ‘How dare you.’"
"He invaded me, he took advantage of me, being who he is, thinking he is all ‘it,’ all everything. He thought he could just do that. I looked at him and said, ‘Don't ever do that again,'" she alleged, claiming the supposed incident occurred "around three summers ago, at Soho Beach House, Miami."
"I have never had a sexual encounter that was not consensual or lawful. Ever," he wrote on Instagram in December, after being accused of rape by four women. "I vehemently deny all these allegations. These horrific accusations have shocked me to my core and all of my relations have been consensual."
