Think all your favorite stars always looked so great? Think again! These 10 ladies went from frump to fab right before our eyes!

Kristen Stewart and Blake Lively might be glamorous red carpet staples now, but just a few years ago these ladies were far more geek than chic. It’s not just the young actresses that have transformed before our eyes, it’s singing sensations like Jennifer Hudson and Carrie Underwood who were totally ho-hum on American Idol, nothing like the hot-hot ladies they are now. And who can believe how stunning Chelsea Clinton looked at her wedding? She didn’t remotely resemble the frizzy-haired teen we all used to know. Angelina Jolie’s cleaned up her act too. Remember when she was super creepy (kissing her brother, carrying blood around her neck and being crazy in general)? Now she’s mother earth incarnate. Check out the other amazing makeovers that have us going, “I can’t believe they looked like that!”
