Porizkova celebrated her 44th birthday on April 9, which would mean she was informed she wouldn't be returning for Top Model'scurrently-casting Fall 2009 edition just over a month ago.
"[Who fired me] doesn't matter, somebody fired me," Porizkova said when Ferguson asked if Top Model host Tyra Banks had been the person to let her know she was being fired.
According to Porizkova, she was fired over the phone.
"But the reason I was fired, just to be fair here, the reason I was told I was fired was because, it seemed that America's Next Top Model had gotten too fat and they needed to cut some fat and the fat was me," Porizkova told Ferguson.
"It's not that I was too fat, I was 'the fat,'" Porizkova told Ferguson when he noted that she was only "skin and bones."
"So I figured it was either that -- I think that was a nice way of putting it and it could have been either that or my gigantic huge ego, which I wasn't aware of before I was told by the producers that I have an ego problem."
"I didn't either," Porizkova told Ferguson when he said he never thought she had an ego problem. "But Tyra... I really believe that just felt they didn't need me, which of course they don't, so that's okay."
Porizkova had been a member of Top Model's judging panel beginning with the show's Spring 2008 tenth edition, replacing former supermodel Twiggy.
Twiggy had been part of the show's judging panel since she had replaced original Top Model judge Janice Dickinson beginning with the show's Fall 2005 fifth season
