It's a very special day for Nick Jonas: he's celebrating his 22nd birthday! It also just so happens to be Transformation Tuesday, so we decided to celebrate Nick's big day by taking a look back on just how much his style has evolved since he was an adorable young curly-haired kid. From his early days on Broadway to his Jonas Brothers music video looks, we've always loved his awesome fashion sense. Now, he's even becoming a real model!
