Tyga's business partner Chuon Guen Lee is suing him for $1.6 million because he has not fulfilled promises regarding their clothing line Last Kings, reports HipHopDX.

According to court documents, Tyga, whose real name is Michael Ray Nguyen-Stevenson, and Lee began Last Kings in January 2013 at which time he agreed to get the clothing line into Tilly's, a chain surf shop, and promote it.

Lee alleges that the California rapper failed to fulfill their agreement and, worse, he walked away from the business to start a new clothing line called Egypt Kings.

The first Last Kings lawsuit against the "Ride Out" rapper was filed by designer Glennon Marrero last year who accused Tyga of stealing his pharaoh design and using it on hats and t-shirts without permission or compensation.

Tyga countersued Marrero, claiming the designer agreed to create the designs in exchange for a 25 percent of the company.

Bossip reports that the lawsuit has not been settled. In April, a process server delivered legal papers to the rapper at his sneaker launch at Shiekh Shoes in Hollywood.

Marrero reportedly seeks profits from articles of clothing using the logo and legal fees.

There could be more legal woes to come for Tyga. TMZ reported Monday that Birdman is furious the "Ayo" rapper encouraged fans to hear tracks off his new album "The Gold Album: 18th Dynasty" on free music streaming services.

The Cash Money honcho believes Tyga made the move to get out of his deal since he wants to sign with Lil Wayne. According to the record label, Tyga purposely prevented sales for the album because fans could listen to it for free.

"The Gold Album: 18th Dynasty" sold a measly 2,200 copies the first week while his previous album had sold half a million copies in the same timeframe.

Rumor has it that Birdman wants another album from Tyga to make up for the financial loss. If Tyga doesn't deliver, sources told TMZ that Birdman is ready to go to court.

Meanwhile, the rapper allegedly still owes $25,000 to model Allison Brown, who sued him in 2013 for sexual battery resulting from her participation in a music video, reports TMZ.

Tyga settled with Brown out of court earlier this year, agreeing to pay her $50,000. She received half in February and nothing more.

She filed court documents in June asking a judge to force the rapper to pay the balance along with a financial penalty, according to TMZ.
