Describing her frustration at the 34-year-old's comments about their marriage she said: "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," she explained. "And it almost gets my hopes up."

Commenting on his transgressions, the enraged TV star said: "He's wearing his ring full time. F*** your ring, you were wearing it when you were f****** someone else too!"

She went on to confess that she had lied to her family to conceal her husband's infidelities.

"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."

Breaking down, she said: "And I didn't have a birthday. I was alone and lied to everyone."
