Lamar Odom is reportedly writing a "tell-all" book to expose of all the Kardashian's family secrets, an attempt to get back at them for leaking his drug abuse struggles, according to the cover of InTouch magazine. 

An alleged source told the magazine that the NBA basketball player, who remains unsigned wants to "destroy" the family, after his life has turned into shambles. He believes that they are responsible for "all the recent public drama," and thinks that "Kris Jenner and the Kardashians planted all the bad stories about him to make him look like a monster."

"If Lamar turns on the family, he could get paid a lot of money - the advance alone would be $5 million," a source told the magazine.

According to the claim, the truth about Khloe's father not being Robert Kardashian could be revealed.

"Lamar knows the truth," a source told the magazine.

With all the bad publicity surrounding him and damaging his image, Odom is freaking out because he's losing everything and may go after Khloe's sister, Kim. 

"Lamar could also expose what Kim's done for money, who she's slept with and the awful things she's said about Kanye West, like how he smells bad in bed and how she's not attracted to him."

"He blames Khloe's family for all the recent public drama. He believes Kris Jenner and the Kardashians planted all the bad stories about him to make him look like a monster. He's deeply depressed and angry. He wants revenge," a source told the magazine.
