14. Miley Cyrus
Talking about makeovers (or makeunders, depending on how you see it), this next celebrity made a huge turn a few years back when she ditched her sweet ‘Hannah Montana’ image (and most of her clothes as well) for a much racier, edgier look, complete with tongue-out selfies and flashy leotards on stage. And with the new look came the new teeth as well: brighter, straighter and more Hollywood-ready. While some might consider her new image an upgrade, we can’t help but love the singer’s cute and relatable look from a few years back a little more than her current one.
