If there's one thing I learned while covering backstage beauty at Mercedes-Benz Fashion Week Spr. '12, it's that short, square-like nails are going to be replaced by long, oval tips this spring (which is already making me anxious because I've become quite accustom to short, stubby nails and they work well with my keyboard-happy profession).

That said, I can't help but think actress Demi Lovato looked like the Grim Reaper while sporting a pair of black talons at a signing for her latest "Seventeen" magazine cover.
