1. Demi LovatoDuring her first season as a judge on "The X Factor," Demi Lovato tried out an array of hairstyles, outfits – and brows? Mid-season, the pop star seemed to have magically grown out her formerly thin arches into a pair of Brooke Shields-esque eyebrows. We now know that she used a hair growth product to aid the growing process (we don’t know if this actually works, so use at your own risk). Either way, we love this look on her! [Photos via, via]
