Rapper 50 Cent has lost a lawsuit against a headphones company who have sued him for $16.1 million.

The Candy Shop rapper – who’s real name is Curtis Jackson – has been ordered by a judge to pay the sum to Sleek headphones after a planned deal to market his own range with the company fell through.

The star reportedly invested more than $1 million to start his line, before deciding to create another set of headphones with a different company.

Court documents reportedly show Sleek were “stunned” when they found the ‘Sync by 50’ headphones were “basically the same design, mechanically” as the pair they had developed.

Sleek also claimed the rapper and his assistants stole confidential information from a website they developed to promote the headphones before they were produced.

Court documents show Sleek sued the rapper for breaching his fiduciary duty, participating in a civil conspiracy, misappropriating trade secrets, breaching his confidentiality agreement and being unjustly enriched.

The rapper instead claimed Sleek “fraudulently induced” him into entering into an investment and breaching their fiduciary duties to him.
