Thomas DeCarlo Callaway (born May 30, 1974), better known by his stage name Cee-Lo Green or simply Cee-Lo, is an American singer-songwriter, rapper and record producer. He originally came to prominence as a member of the southern hip-hop group Goodie Mob, later launching a critically acclaimed solo career and forming Gnarls Barkley with DJ/producer Danger Mouse.
Internationally, Green is best known for his work within the hip hop duo Gnarls Barkley and their worldwide hit "Crazy" (2006), which reached number one in various singles charts worldwide including the United Kingdom. In the United States, "Crazy" reached number two on the Billboard Hot 100. The parenting album, St. Elsewhere was also a hit, reaching number one on the UK Album Charts and charting at number four on the US Billboard 200 album charts. The duo's second album, internationally less successful, The Odd Couple (2008) missed the top ten in both the UK and US, where it charted at number 12 in the US, and 18 in the UK.
Green, taking a break from recording with Gnarls Barkley, released the single, "Fuck You!" on August 19, 2010 as a solo recording artist. The song was an instant hit, reaching the top spot in the UK and the Netherlands and charted at number two on the US Billboard Hot 100. The parent album, The Lady Killer (2010) saw similar success, peaking within the top five of the UK Album Charts and debuting within the top ten on the Billboard 200 album charts, and received a Gold certification from the BPI in the UK shortly after its release. The second single, "It's OK" was a hit in Europe, and the third single, "Bright Lights, Bigger City" has also seen similar charting success. Green is currently a vocal coach on the NBC reality talent show The Voice with Adam Levine, Christina Aguilera, and Blake Shelton
