Later on Friday, she took to Instagram and shared a photo of her growing baby bump, along with a story about her quest for all things healthy while pregnant.
‘As soon as I found out I was pregnant one of the first things I did health-wise was start looking at what I was putting in my body and on my body, from food to lotions, oils, beverages and especially vitamins.I wanted to find the most natural things I could with the fewest ingredients,’ she wrote in the caption.

The actress continued: ‘I did my research and tried a handful of different prenatal vitamins; some made me feel sick, some didn’t have all the things I was looking for (Choline was missing from quite a few) and just recently discovered @shakleehq Meology Prenatal and decided to give it a try because I was really impressed with the clean ingredients.’
