Lately we’ve noticed quite a few female celebs wearing their hair in topknot buns. Piling all the strands you’ve got on top of your head seems to be the thing to do these days, from Jennifer Lopez‘s knotty beehive at a premiere for “The Back-up Plan” to Kate Hudson‘s errand-running updo. E! hilariously called this look “funky cinnamon-roll hair,” and we can’t decide how we feel about the hairstyle. Take a look at celebs rocking topknots, then tell us if it’s a hairdo or a hair don’t.
