Viacom billionaire Sumner Redstone is having the worst year ever! Just over three months after RadarOnline.com released tapes of him begging a former lover to join him at an orgy, a new report claims a different ex is planning to write an explosive tell-all.
Christine Peters, who dated Redstone in 1999, told Page Six that she was planning a juicy memoir about the "crazy, genius dysfunctional" people she crossed paths with during her time in Hollywood.
"Christine was an eyewitness to Sumner's decline and how people took advantage of him," an insider told the Post.
But whatever she reveals, it will be hard to top the X-rated revelations of Radar's exclusive audio of Redstone, 92, published earlier this year.
As Radar reported, the kinky nonagenarian left explicit voicemails for a former lover describing what he wanted to do with — and to — her.
"How's my hot piece of ass?" he asks in one raunchy message. "I have a question. Do you have a man you can trust who's a nice-looking nice person who'd like to engage in a foursome or fivesome?"
"That would be very hot," continued Redstone. "I'm sure there must be a million women who want to f**k you…let me know if you have a man that you would recommend, that you would trust. Nice looking, nice person, not a slutty guy, who would join us."
In a different message, he asked her to join him for an orgy.
"Bob's never done a threesome with two men. He's done it with three women. So he's a little bit nervous but he's gonna come cuz I want him to," Redstone told the woman, before he explains what to expect next.
"So what will probably happen will probably really excite you. I'll f**k her and she'll suck Bob off and he'll f**k her and she'll suck me off," mapped out Redstone.
"Before that, I'll make her jerk off in front of Bob because she's very hot when she jerks off," he explained. "She's better than what you do. She takes a long time and she moans."

In yet another message, he regaled her with his X-rated plans.
"Of course I love you. I wanna f**k your ass off," he gushed. "You know what? I can arrange for you to participate on Friday. I think you want it. I know you're shy but you said you want it…Sucking another male partner off. It would get me very happy if you did it. Then we're gonna have a real future of sex. So let me know on my cellphone if that's ok and I'll arrange to have you picked up."
