Watch Khloe Kardashian Reveal The Heartbreaking Details Of How Lamar Odom Cheated

'F--k your ring. You were wearing it when you were f--king someone too,' Khloe says.

Khloe Kardashian said that this upcoming episode of "Keeping Up With the Kardashians" would be tough to watch, and she was right.

In a clip teasing Sunday's show, Khloe confirms all those rumors that ex-husband, Lamar Odom, did in fact cheat on the reality star. As Khloe is cleaning out her closet and moving things out of her home she once shared with Lamar, she has an emotional chat with her sister Kourtney.

"Do you know the interviews he's doing saying that being married to me were the best years of his life, he's now wearing his ring full time. F--k your ring. You were wearing it when you were f--king someone too," Khloe revealed. "He doesn't think we are going through with a divorce."

Khloe, who filed for divorce in December, was referring to a press conference Lamar did back in February for his new basketball team, Baskonia.

"I love my wife. She'll always be my wife, no matter what," Odom, who was caught on video rapping about cheating on Khloe, said. "Who knows? We don't know exactly if [the divorce is going through]. Only time will tell. I hope not. But even if we were divorced, she would always be my wife."

Khloe found these comments not only untrue, but they gave her false hope that things would change in the future.

"Saying he talks to me every day or that we are working things out and I feel like people are almost questioning have I done enough? But I can't reach him for months on end," Khloe said. "I would just rather him not say anything because it almost gets my hopes up and then nothing ever changes."

Viewers can clearly see how much this relationship has taken a toll on the youngest Kardashian sister, who was married to Lamar for four years, and what lengths she went cover up his infidelity.

"The 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," she said, before later revealing, "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 messing with another girl, OK? And I lied and I gave up my Beyonce tickets to Kendall that's how badly I was hiding."

Khloe isn't hiding her new relationship, since she has been stepping out with rapper French Montana. The two made their first official red carpet appearance last week, celebrating her 30th birthday in Las Vegas.
