Jennifer Lopez's first husband Ojani Noa has accused her of cheating during their marriage

Noa - who was married to the Kiss of the Spider Woman actress for 11 months between 1997 and 1998 - wrote in a post on Instagram: "Stop putting us down. Stop putting me down with your victim card. The problem is us. Not me. The problem is you. You're the one who couldn't keep it in your pants.

"You have been 'loved' a few times. You have been married 4 times. And have had countless relationships in between. You've had good relationships... Me for example."

Noa, 51, claims to have moved out of the state to support J.Lo as well as leaving his family and job in order to care for her.

He wrote: "You chose fame and fortune and moving apart of our relationship.

"You decided to lie, to cheat on me and even though I stayed. I even tried to keep the marriage going and alive. You even begged me to stay because at the time you didn't want bad press caring more about you."

Noa did not elaborate on the cheating claims but accused the Let's Get Loud singer of caring more about "the fast line of her career/stardom" than him.

He said: "I couldn't stay anymore and deal with the constant lying. That's why I left you. That's why I divorced you."

Noa added: "Tell the truth for once. Let people know you are the problem. You should be embarrassed, ashamed of yourself."

Lopez has been married on four occasions but explained to Stern that none of her relationships have felt "doomed from the beginning".

She said: "I live my life very out loud, even though I was in the public eye, and I wanted to share my life with someone.

"I want someone to be there when I'm having big important moments on the red carpet. I want someone to be there when I'm doing whatever, or when we're going to the store."
