The Lollipop hitmaker launched a $51 million (£32 million) lawsuit against Cash Money bosses Bryan 'birdman' Williams and Ronald 'Slim' Williams in January (15), accusing them of withholding money he was owed for his album Tha Carter V.
Wayne, real name Dwayne Carter, Jr., has filed new documents claiming artists on his Young Money label, an imprint of Cash Money, also suffered non-payment issues.
In the legal papers, Wayne claims he has a letter from Drake and Tyga's team alleging the rappers are also owed money, and another from Minaj's representatives claiming her producers were shortchanged for their work.
Wayne also accuses Williams and his brother of keeping a $100 million (£62.5 million) advance which was supposed to be given to the Young Money label.
The Williams siblings have denied the allegations, according to TMZ.com.
