Usher turns 37 on Wednesday, so what better way to celebrate the seductive star than with a look at some of his hottest moments? The singer is known for his stellar physique and amazing six-pack, but that's not all. Over the past few years, we've seen Usher transform from pop star to doting dad with his sons Usher Raymond V — who goes by Cinco — and Naviyd. We couldn't possibly highlight Usher's sexiness without his sweetness, so we've rounded up photos showing both of his amazing sides. Happy birthday to Usher!
