Khloe Kardashian admits: 'Lamar cheated on me on my birthday'

Khloe Kardashian has come clean and admitted that her ex-husband Lamar Odom cheated on her while they were married.

In a new preview for Keeping Up With The Kardashians Khloe reveals that she spent her 29th birthday alone because Lamar was with another woman – something she had previously tried to cover up.

Clearing out her wardrobe at the home she once shared with Lamar, she tells Kourtney: ‘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,’ she continues. ‘Everything I did I had to hide or conceal or cover up.’

And that wasn’t the worst of it…

‘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?

‘I lied and I gave up my Beyoncé tickets. That’s how badly I was hiding. I didn’t have a birthday. I was alone and lied to everyone.’
