Khloe Kardashian is extremely upset at her mom, Kris Jenner, for allegedly defending her ex-husband Lamar Odom, multiple sources confirmed.

On Sunday night's episode of "Keeping Up with the Kardashians," Khloe found out that her mom continues to keep in touch with Lamar, according to Radar Online.

During the start of the episode, Khloe reached out to her mom and told her that she wants to keep in touch with Lamar, mainly to ask him to leave her alone. At one point, Khloe finds out Kris' connection to Lamar and she flipped out.

The mom and daughter tandem end up arguing over the former NBA superstar. Jenner said, "He probably just wants things to go back the way they were."

Khloe responded, "You always stand up for him!" Her mom fired back, "I'm not taking his side. I'm not buying what he's saying. I'm just telling you that I love him very much and I want him to be okay."

To this, the 30-year-old Khloe completely went crazy and snapped, "He's available if you want to f*ck him and date him!"

The confrontation between the two ended after Khloe explained to the viewers, "It's kind of heartbreaking when your mother doesn't take your own side."

Other than the controversial argument between Jenner and Khloe, the latter also expressed her dismay over Lamar still wearing their wedding ring and telling media publications that the best years of his life were those he spent with Khloe, Inquisitr noted.

"F*ck your ring, you were wearing it when you were f*cking someone else too. They way I was living is not a way to live! I kept in hiding every time there was something going on. I would have to lie, or conceal, or cover up, and I'm so over it!" Khloe exclaimed.

Talking to her older sister Kourtney, Khloe added, "Let me tell you something. Last year on my birthday I lied to everyone because I had to lie and say I was with my husband, when, in fact, my husband was missing with another girl!"
