In the clip, Khloe is talking about Lamar claiming they’re working on their relationship.
She says: “Lamar is doing all this press because he is on a new team. But what he is saying is just not true. Saying that he talks to me every day and that we are working things out.
“But I haven’t been able to reach him for months. And it almost gets my hopes up.”

“He’s wearing his ring full time. F*** your ring, you were wearing it when you were f****** someone else too!”
Khloe then confesses all, saying: “The way I was living was not a way to live. 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. Okay?
“And I lied and I gave up my Beyonce tickets. That’s how badly I was hiding. And I didn’t have a birthday. I was alone and lied to everyone.”
