It was definitely a wig. I think it was very obvious. As far as coloring the hair when you are pregnant, that is not so much true any more, maybe back in the day when the hair color was so much more stronger and basically they only said that because of fumes, but the way hair color is today there is no worries. Especially since you know she isn't doing it at home out of a box. She is using professional products to get her hair colored I am sure, so even her highlighting thru out the pregnancy is not harmful.
