Lamar Odom admits he threatened to kill Khloe Kardashian, claims she 'beat up' mistresses

Disgraced NBA player Lamar Odom has confessed he once threatened to kill his ex-wife Khloe Kardashian while in a drug-induced psychosis.

In his new memoir Darkness To Light, Odom dishes on his fraught relationship with the Keeping Up With The Kardashians star, detailing an incident where she "beat the shit" out of a stripper.

Odom said he owed the entire Kardashian clan an apology, "big time", adding he once yelled at his former wife: "I'll f**king kill you. You don't know what I'm capable of". 

He called the incident "the most regrettable moment in a series of regrettable moments".

"I'm pretty sure she had to be scared at that point in time. I'm thinking about it now, like, I couldn't believe how I was treating that queen like that."

The Lakers player opened up about his history of drug abuse and sex addiction in an interview with Good Morning America, admitting: "I was a professional at hiding it".

"You don't want your wife to know that you're sniffing coke and... having sex with other women."

Odom also explained that Khloe and her mother Kris Jenner once burst into a hotel room where he was engaging in group sex with several women.

"[She] opened the door and pounced on the first girl she saw," he wrote of Kardashian.

"Beat the shit out of one of the girls who tried to protest. She's dropping vicious blows all over the top of this girl's head," he said.

In 2015, Odom nearly died from a drug overdose after he was found unconscious at a Nevada brothel.

The Kardashians have yet to publicly address the claims.
