Lil WayneLil Wayne is no stranger to lawsuits, even if he’s behind bars. The latest comes from producer Jim Jonsin, who claims the rapper owes him money.

According to a New York Post report, the producer has hit Weezy (real name: Dwayne Carter, Jr.) with a lawsuit over royalties for the rapper’s hit single, “Lollipop,” which he produced.

He claims he’s yet to receive a royalty check from the single, even though it’s one of biggest singles the rapper’s ever had.

Jonsin is suing for $500,000.

Earlier this year, Lil Wayne was sued for $2.5 million for copyright infringement over his single, “Mrs. Officer,” after the song’s producer said the rapper and his label stopped paying him royalties for the single.

Before that, in 2008, he was sued by Karma Ann Swanepoel and her publishing company over samples used on Weezy’s widely distributed track, “Dying.” They claim the rapper samples her song, “Once,” without permission or consent.

Both lawsuits are pending.
