Poor Kendra?

We've all been giving Kendra Wilkinson a lot of credit. She went from being one of Hugh Hefner's 3 girlfriends to being a wife and a loving mom. She turned her entire life around. But now another of Hugh's exes, Karissa Shannon, is writing a tell-all that will expose a lot of Kendra's dirty secrets. Are you ready?

We didn't think there was anything Kendra Wilkinson hid. After all, she was on a reality show detailing her life as Hugh Hefner's live-in girlfriend. And she recently came out with a book giving us tons of details about what really went on. But Karissa Shannon says Kendra is hiding a lot from us. And she's ready to give all the details.

You know Karissa as being one of the twins who was recently dumped and kicked out of the mansion by Hugh Hefner. You also know there's allegedly a sex tape floating around starring Karissa and Heidi Montag. But soon there could be a book from Karissa floating around, too. She's saying she wants to expose Kendra Wilkinson. Karissa tells Life & Style magazine, "Kendra's always been really jealous of me... Kendra is definitely scared."

We are seriously curious about what this book is going to contain! Karissa says she saw Kendra doing things at the mansion that "no one would believe." Like? We wonder if it's mostly drugs and sex... We can't really think of anything else! And we are so proud of Kendra's achievements, we don't want to believe any of it.

Plus, we have to wonder how reliable a source Karissa is, especially in light of her involvement with Heidi Montag and Spencer Pratt. Plus, she seems to have a serious grudge against Kendra and says, "It seems like she always has negative things to say... I think it has to do with having the baby-maybe she's a little more insecure about her weight and her relationship with her husband now that her ex-boyfriend released a sex tape of her."

Could Karissa just be jealous that Kendra moved on from the  mansion and is now happily married with an adorable baby? After all, it was Kendra who chose to leave, while Hugh kicked Karissa and her sister out.
