Bobby Brown’s getting into the business of selling books with some pretty wild storytelling in his forthcoming memoir.

The New Edition member's Every Little Step is due out June 13, however the Associated Press got an early copy and spilled some "WTF" everywhere. According to an excerpt, Brown claims his ex-wife, Whitney Houston, cheated on him with Tupac Shakur.

“He contends that she did her ‘share of cheating’ with ‘quite a few of the producers and artists’ she worked with,” writes the AP, “And names one ex-lover, the late Tupac Shakur.”

Wow. The AP’s findings also uncovered that Brown admits he had affairs with Janet Jackson and Madonna and numerous run-ins with the law. He opens up about his own drug problems but pushes back against his involvement in Houston’s struggles with narcotics. He did the same during a recent interview with 20/20.

It seems Bobby Brown is claiming he’s been on the fringes but denies anything incriminating. In Every Little Step, he claims he smoked weed with his late daughter, Bobbi Kristina, but didn’t contribute to her struggles with drugs either.

Whitney Houston's side of the story will unfortunately not be told, since she passed away in 2012. Bobbi Kristina died just last year. Read the AP’s full report here.
