After Khloe says Odom has been wearing his wedding ring full-time, even though she already filed for divorce, she says "F--- your ring, you were wearing it when you were f---ing someone else too."
She added that Odom was saying "being married to me were the best years of his life," even though she couldn't reach him for months at a time.
"He doesn't think we are going through with the divorce," she adds. "I'll always be his wife and he'll never call me anything else. Whatever, now he's finally admitting he's done f---ed up s---."
She continued, "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!"
