Melanie and her twin sister, Katherine, may have known about the alleged affair, according to the story which quotes an affidavit filed by John Oudin.

"Both [Melanie and Katherine] asked me point blank if I thought Mom was having an affair with Brian. When I asked why they had suspicions, Melanie told on one occasion she woke up at 1 a.m. in her hotel room and Leslie was not there. She called Brian's cell phone and connected with her."
