Mary J. Blige Rocking Vintage Roll Updo Hairstyle. Mary J has always played around with different hairstyles to create fab and unique looks, and recently been spotted several times wearing a rolled under updo. Her first appearance with the style featured all of her hair pinned to one side and rolled under, and her second appearance included the style being parted down the middle and both sides rolled up under. Whether you’re digging the look or not, Mary J is, and she’s been rocking the style since early June. Are you loving Mary’s vintage rolled updo?
