'Lamar cheated with another woman on my birthday, & I lied to cover for him' - Khloe K

In a new preview for Keeping Up With The Kardashians, Khloe Kardashian confessed that her now ex-husband Lamar Odom cheated on her with another woman on her birthday last year and she lied to her family to  cover for him.

"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 everyday 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! The way I was living was not a way to live. Everything I did I had to hide or conceal or cover up.'

"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.'
