OK! Exclusive: Khloe Kardashian's Romance With James Harden Is 'Tearing Lamar Apart' — The Truth Behind Their 'Secret' Meeting!

When Lamar Odom was seen in the early morning hours confronting his ex-wife Khloe Kardashian earlier this month, most shocked fans were shocked he ambushed the reality star. But apparently, their secret meeting was planned though things did not go as expected after Lamar began expressing his outrage over her new relationship with NBA star James Harden!

A source tells OK! exclusively, “the relationship is a slap in the face to Lamar. He and Khloe essentially broke up because he was cheating and now she’s with a man who’s notorious for being a womanizer!”

James has already been accused of cheating on Khloe with a blonde Australian beauty, and he’s known to date only music industry vixens, including Kyra Chaos and Maliah Michel.

The source continues, “Lamar told her ‘He’s worse than I ever was,’ and Khloe couldn’t take it. She called him a hypocrite and told him to back off.’” That scene is probably what witnesses saw when Khloe yelled for Lamar to get off of her before jumping back in her vehicle and driving away from the SoulCycle studio they met at.

James and Khloe just started dating a couple of months ago, but it already looks like their romance may be the real deal. He’s attended a number of family functions, including Kylie and Kendall’s high school graduation and Kylie’s birthday bash. And Lamar clearly is not happy.

The romance is “tearing Lamar apart,” says the insider. “He feels like this upstart came out of nowhere and stole his life.” It probably does not help matters that they are both in the same profession, or used to be. Lamar used to be a renowned LA Laker prior to his battle with drugs.

So what’s Lamar’s next move? He may write a tell-all book! “He’s got some real dirt on the Kardashians. It’s not something he would have considered before, but his career and love life are in tatters, and he feels he’s got nothing to lose.”
