The mother of Tupac Shakur has filed a $1.1million (£685,000) lawsuit against Entertainment One for failing to pay royalties from an album released after the rapper's death.
Afeni Shakur is claiming that the media company owe her millions from the star's album Beginnings: The Lost Tapes, released in 2007.
The record contains 10 tracks recorded by the hip hop star at the start of his music career in 1988.
As the co-administrator of her son's estate, the 66-year-old is also demanding that Entertainment One turn over master recordings of all of her son's unreleased music, TMZ reports.
Entertainment One bought the rights to the California Love hitmaker's music in July from previous owners Death Row Records.
"Although DRR [Death Row Records] retained physical possession of the unreleased Tupac material, it had no ownership rights in and no right to sell, license, or otherwise exploit any of the recordings or underlying compositions therein, and plaintiffs are the exclusive owners of all intellectual property rights with respect to the unreleased Tupac material," the 11-page lawsuit states.
Tupac died in September 1996, six days after being shot multiple times in a drive-by shooting. He had been driving in Las Vegas after watching a Mike Tyson fight.
The rapper is one of the highest-earning deceased celebrities in the world, with more than 75 million albums sold to date.
