When Sisqo, the lead singer of Dru Hill -- known for their commanding gospel vocals and untouched R&B classics -- went solo, no one was expecting the transformation he went through.

With platinum blond hair, Sisqo wanted all of our attention as he released his debut album, 'Unleash the Dragon.'

He also made our eyes open even wider when the bad boy gave us the overplayed 'Thong Song,' in which he sung patiently about the skimpy form of underwear.

The song eventually reached No. 2 on the Billboard Hot 100. This effort was a record label's dream, but everyone else's nightmare -- those who hated the track surely tried their best to change the station when the son came on the radio.
