Lil Wayne has been slapped with a lawsuit by a producer who claims that he's owed thousands of dollars for the song 'Mirror.'

The chart-topping track, which features Bruno Mars on the hook, appeared on Weezy's 2011 album, 'Tha Carter IV,' which has sold over 2 million copies in the U.S.

According to TMZ, producer Ramon Owen (aka REO) of the production crew the Soundkillers, claims that he produced 'Mirror' and was promised royalties from the sale of the song.

The 30-year-old studio maverick states in his suit that Young Money sent him a statement showing him that he's due $91,000 for his services. But as of now, REO has received "zero" funds for his work. Now he wants Wayne to pay up.

In a 2011 interview with MTV News, REO explained that the 'Mirror' beat fell into the hands of several prominent rappers but Wayne was the one who snatched it up.

"[Kanye West] heard it, Drake heard it, and it already had the Bruno [hook],” he said. “Basically, Nas had it for a while, and it just ended up in the hands of Wayne and he loved it.”

In the past few years, Wayne has been sued by a multitude of producers. In 2011 alone, the 'Believe Me' rapper had at least five different lawsuits pending by producers who claim they haven't received royalties for their work on several Wayne albums.

Attorneys for Lil Wayne had no comment on his recent legal case.
