Warren Anderson Mathis (born March 6, 1977), better known by his stage name Bubba Sparxxx, is an American rapper. His 2001 single, "Ugly" (featuring Timbaland) peaked at number 15 on the Billboard Hot 100 and led him to sign with Timbaland's Beat Club Records, an imprint of Interscope Records to release his debut studio album, Dark Days, Bright Nights (2001). A critical and commercial success, it peaked at number three on the Billboard 200.

His second album, Deliverance (2003) was met with further critical acclaim, while his third, The Charm (2006)—released by Big Boi's Purple Ribbon Records, an imprint of Virgin Records—yielded the single "Ms. New Booty" (featuring Ying Yang Twins and Mr. Collipark), which peaked at number seven on the Billboard Hot 100. This marked final release on a major label, and his subsequent releases delved further into country rap.

Mathis grew up in Troup County, Georgia, in a rural area near LaGrange. He is of French descent. His father was a school bus driver and his mother was a grocery store cashier. His closest neighbor, who lived half a mile (0.8 km) away, introduced him to rap music through mixtapes mailed from New York City. The music of 2 Live Crew was his introduction to hip hop; he began listening to West Coast gangsta rap such as N.W.A and Too Short and the Atlanta duo Outkast. With rapping as a hobby, he was a tight end and linebacker for his high school's football team and earned All-Region honors in his senior year. Steve Herndon, a former offensive lineman for the NFL's Atlanta Falcons and Denver Broncos, played football with him during high school, according to an interview with Down-South.com. In 2007, he moved to Tampa, Florida.

In 1996, he moved to Athens where he met industry veteran Bobby Stamps. Stamps noticed him rapping after a University of Georgia football game and later introduced him to Atlanta producer Shannon Houchins.

For two years, Houchins and Stamps worked together to produce Sparxxx's first commercial release, Dark Days, Bright Nights, which released in 2001. The debut album saw some success in Georgia and caught the attention of Jimmy Iovine of Interscope Records. Sparxxx signed to Interscope and began working with record producers Timbaland and Organized Noize, as well as continuing to work with Shannon Houchins. The major-label reissue of Dark Days, Bright Nights, released via Timbaland's Beat Club Records imprint and which now included five collaborations with Timbaland and two with Organized Noise, debuted at #3 on the Billboard 200.

In 2002, he had a minor hit being featured on Archie Eversole's "We Ready", which became popular for being played at sporting events, such as American football and basketball games. In late 2003, he returned with his second album, Deliverance, which was critically acclaimed but sold poorly.

Sparxxx signed a recording contract with Virgin Records in 2004; under Virgin, Sparxxx released The Charm with singles "Ms. New Booty" and "Heat It Up".

He left Virgin to establish his own label, New South Entertainment, which is distributed by E1 Records. In 2007, he released a mixtape with DJ Burn One titled Survive Till Ya Thrive.
