Khloé Kardashian isn't holding anything back.

The 31-year-old reality star is releasing a new tell-all book, Strong Looks Better Naked, detailing her fitness journey — and she had a lot to say about Lamar Odom.

“The thing is, you can’t control other people, and you can’t control the outcome of situations,” Khloé writes, “and if you think you can, you will soon discover that you are sadly mistaken.”

Of course this book was written before the reality star decided to reconcile with her estranged ex after he was hospitalized for an alleged drug overdose. Khloé hasn't left Lamar's side following his recent hospitalization, even taking a break from filming Keeping Up With the Kardashians to focus on his recovery.

Their marriage initially collapsed after the former Laker was traded to the Dallas Mavericks in 2011 — and Khloé struggled to deal with the constant cheating and drug rumors surrounding her man, according to Page Six.

“Every day felt like an attack,” she admits, adding that the paparazzi constantly questioned her if Lamar had been unfaithful. “It was also humiliating; it got to the point that leaving my house would give me social anxiety.”

Despite all the drama, it's obvious Khloé wants to keep the love alive, ending the book thanking Lamar for the best years of her life.

"Before I met you I felt invisible, and after I felt seen.”
