"I would like to apologize to my husband," she added. "This was not planned. I'm just so hormonal."

A few months later, she revealed in an interview with "CBS This Morning"that she was feeling the effects of her pregnancy.

"I'm familiar with all-day sickness," she told host Gayle King. "I have to get IVs and fluids because I get so dehydrated. It's really bad."
