Usher turns 35 today, 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 35 photos showing both of his amazing sides. Happy birthday to Usher!
