Karissa Shannon Talks Tell-All Book

“I’m working on a new book right now. It’s an autobiography. It’s going to include things about life at the mansion,” the 20-year-old blond told Hollywood Life exclusively at OK! magazine’s fifth anniversary party Sept. 1 in Hollywood. “[It was reported] that it was a tell-all about Kendra, but that totally got twisted. Kendra is involved in it because she was at the mansion at the time.”

The book WILL delve into the seedy underbelly of the Playboy mansion, though. “There’s a whole other side of Playboy that nobody knows and I’m going to be able to explain,” she tells us. “[I'm going to write] totally unexplainable things that nobody would ever expect. It’s the Hef that no body knows. It’s the Hef that I know personally. Kendra might not have wanted to talk about it, but I’m willing to talk about it!”

While Kendra seems to be safe from harm, Karissa is more than willing to diss the other Playmates. “The other girls had things against us because we kind of took over their show,” she says of Bridget Marquardt and Holly Madison. “[My twin sister Katrina and I] are the younger and better looking Playmates. They’re all kind of old and they put in all the work to make the show. We just kind of came in and took over. So there’s a lot of jealousy going on there, but I don’t have a problem [with Holly].”
