Hip-hop star Tyga is reportedly facing a $1.6 million lawsuit from a former business associate.

The Rack City hitmaker, real name Michael Nguyen-Stevenson, is said to have set up a clothing line called Last Kings in 2013 with businesswoman Chuon Guen Lee.

She claims that Tyga promised to promote the business and get it stocked by popular California-based retail company Tilly's.

Editors at TMZ.com report that Lee states in legal documents that Tyga failed to follow through with his assurances and allegedly took merchandise worth more than $500,000 when the deal fell through.

Lee is now suing Tyga for $1.6 million plus damages, after he set up Egypt Kings, a rival and similarly-named clothing company.
