Rap star Lil' Kim, convicted of perjury and conspiracy in March, has been sentenced to a year in jail for lying to a grand jury to protect friends.
Lil' Kim has been jailed and fined for lying to a grand jury
The jury was investigating two of her associates involved in a 2001 shooting outside a Manhattan radio station.
She had faced up to 20 years in jail on three counts of perjury and one count of conspiracy.
Lil' Kim, 29, is thought to be the first high-profile female rap star to be sent to prison in the US.
Before her sentencing in New York, the Grammy-winning artist made a plea for leniency, admitting she had done wrong.
"I testified falsely to the grand jury and during the trial. At the time I thought it was the right thing to do. Now I know it was wrong," she said in court.
Lil' Kim, real name Kimberley Jones, was also fined $50,000 (£28,000).
She won a Grammy in 2001 for her part in the hit remake of Lady Marmalade alongside Christina Aguilera, Pink and Mya.
Charges were brought against her after a gunfight erupted outside the Hot 97 radio station in 2001 as a rival rap group was arriving.
Jones and members of her rap group Junior Mafia had been guests on the station.
As they left the building, a shootout broke out between members of her entourage and rival group Capone-N-Noreaga.
The group had challenged their rivals about an insult aimed at Jones by another female rapper, Foxy Brown, in a song called Bang Bang.
Lil' Kim was accused of lying numerous times in 2003 court appearances when she told a grand jury her ex-manager was not at the station on the day and denied knowing a former bodyguard.
Both admitted they were there and pleaded guilty to gun charges.
One man was injured in the shootout, which happened at the same radio station where rapper 50 Cent was involved in a gun battle in March this year.
