Last week, the “Cosby Show” star announced she and husband, Ed Hartwell are expecting a baby girl and just a few days later, Hartwell filed for divorce.

On Wednesday night, Pulliam sat down with “Entertainment Tonight” and opened up about her whirlwind romance and quickie divorce, and she spilled allegations of her own against Hartwell. Pulliam maintained that she “never cheated on him during my marriage” and accused Hartwell of being unfaithful to her.

“That’s not who I am,” she said. “That’s not an issue. There’s no problem. I’ve never been unfaithful to my husband. This is his daughter.”

“When earlier in my marriage I was faced with this, I was ready to leave,” Pulliam continued. “I had divorce papers ready. I presented them to him. He begged … He said: ‘Please, I want my family,’ he said all the right things. Once I was pregnant I decided to give him another chance.”

She confessed that she felt completely blindsided when he decided to leave.

“He left like it was any other day, said goodbye, I was still asleep in bed,” she said. “He texted me saying: ‘Hey, can I talk to you for a moment,’ … He was like: ‘You know, this isn’t working.’ All I heard was: ‘I filed for divorce this morning and I’m coming to get my stuff.'”

Now that Hartwell is out of her life, Pulliam said she plans to focus on her daughter.

“It’s one thing when you choose to be in the spotlight. It’s another thing when you have a baby. And it’s not about me,” she explained. “The biggest thing and my priority is she doesn’t deserve it.”

As for the possibility of getting back together with Hartwell, Pulliam isn’t taking any chances.

“I have no desire to continue to be married to him.”

Pulliam’s interview on “Entertainment Tonight” continues Thursday night.
