Hip-hop star Akon has embellished his criminal history, according to a report.

The 35-year-old singer is not the gangster rapper he says he is, having only served several weeks in jail rather than the years he's claimed, the Smoking Gun reports.

The Web site conducted an investigation into his claims of having done three years of hard jail time in the late 1990s for his role as the "ringleader of a notorious car theft operation" and found that instead, he was arrested in 1998 for driving a stolen car in Georgia and served five months in jail before the charges were dropped.

Last year, Akon did run into criminal problems when he allegedly tossed a fan off a stage during a concert. Concertgoers said that a spectator lobbed something at Akon during his performance at Dutchess Stadium in Dutchess County, N.Y., in June 2007.

They said the singer asked the crowd to point out the culprit and a security guard picked out a 15-year-old boy and sent him up to the stage. Akon then hoisted the teen onto his shoulders and flung him into the crowd.

The incident was captured on videotape and Akon appeared in court in Fishkill, N.Y., in December.

The boy landed on Abby Rosa, who told the Poughkeepsie Journal she was later found to have suffered a concussion.

The musician was criticized in April of last year for having simulated sex with a 14-year-old girl on stage at a concert in Trinidad. He apologized later and said he didn't know the girl was underage.

Akon's latest album, "Konvicted," has sold more than 1 million copies in the United States. His hits include "Don't Matter," "I Wanna Love You" with Snoop Dogg and "Smack That" with Eminem. At the recent American Music Awards, he won favorite male soul/rhythm & blues artist.
