The mom-to-be spoke to ET this week about her troubling ailment which, seven months into her pregnancy, landed the 32-year-old model in the hospital.

"I was really vomiting a lot during the day, it freaked me out," Madison said. "I was told to go to the doctor and get an IV and everything. So, that was kind of scary to me just because it seemed like something so unusual...but everything's O.K. so far, so that's good."
