"
21 Questions" is a song performed by American
rapper 50 Cent and
Nate Dogg. The song was written by 50 Cent, K. Risto, J. Cameron, and V. Cameron for 50 Cent's commercial debut album
Get Rich or Die Tryin' (2003). Released in 2003 as the album's second single, it became his second number one song in the United States, after "
In Da Club". It reached #6 on the
UK Singles Chart while "In Da Club" was at No. 23, giving him the rare feat of having two singles in the Top 30 at the same time. The track was produced by Chris styles and samples elements from
Barry White's "
It's Only Love Doing Its Thing". This was the only single from the album to not have the
Parental Advisory sticker on its cover since the only profanity was the word "nigga" in the first verse.
