"Do You" is a 2007 single by American singer-songwriter Ne-Yo. It is about Ne-Yo questioning his ex-girlfriend if she ever thinks about him anymore. It is the second single from his second album, Because of You. The single was officially released to radio the week of June 12, 2007. In an interview with BET, Ne-Yo said that "Do You" is the second part to his song "So Sick" from his debut album, In My Own Words.
"Do You" was released on July 30 in the UK as a download only single, despite receiving more video play than follow-up single "Can We Chill" (which received a physical release), resulting in a lower chart position of number 100 there, his lowest charting single.
