It's totally over between Khloé Kardashian and Lamar Odom!

In Touch can exclusively reveal that the reality star — who is now dating NBA star Tristan Thompson — is beyond done with her ex after refiling for divorce last year.

"They’ll never speak again,” says a source close to the situation. “The old Lamar is not there. He’s a new person completely and someone Khloé doesn’t recognize.”

Our insider adds that she was "hurt" that the disgraced athlete revealed he wants more kids after they "tried for so long."

Khloé originally filed for divorce in 2013 after four years of marriage thanks to infidelity and substance abuse on Lamar's part. Two years later, she revoked her request when he suffered from an almost fatal drug overdose.

Lamar recently completed a rehab stint as a precautionary measure to avoid a relapse around the holiday season. While it's unclear if he is dating anyone at the moment, he has been spotted out with a Koko lookalike.

Meanwhile, his ex is as happy as a clam in her new relationship with the Cleveland Cavaliers basketball player, who she was first romantically linked to back in September.

“I’m in a really good space right now in my life. I feel really happy and secure and I’m just in a really positive, healthy relationship,” she previously revealed on The Talk. "I love routine. It’s a normal routine life. I love to cook, so I get to cook dinner every day. It’s this home, family thing that I’ve been craving that I get to have in Cleveland.”
