Rihanna and Jay Z may have a lawsuit on their hands. The Run This Town collaborators are being sued by a concert promoter in Nigeria who claims the musicians cancelled a gig and pocketed the money. However, Jay Z's Roc Nation record label refute the allegations and say the promotion company most likely fell victim to a scam.

According to TMZ, Chris Ubosi from Megalectrics has filed a lawsuit against Rihanna, 28, and Jay Z, 46, alleging that they were scheduled to perform in May 2013. Ubosi claims he agreed a deal with two people who said they were from Roc Nation and represented Rihanna and Jay Z.

The deal allegedly stated that Rihanna would receive $425,000 (£291,000) to perform a 65-minute show and Ubosi claims to have made three payments totalling $160,000 to the Work singer. Rihanna's team are later said to have contacted Megalectrics to postpone the concert and Ubosi agreed on the condition that the pop star would announce a new date via social media.

Megalectrics say the social media announcement was never made so the company cancelled the event completely and demanded that their money was repaid. Ubosi says he has never received the fee, prompting him to file the lawsuit.

The lawsuit may not sway in Ubosi's favour as Roc Nation have responded to his claims and say neither Rihanna or Jay Z were in contact with his company. A statement from the record label said: "Rihanna, Roc Nation nor anyone associated personally or professionally with either party was in contact with this person. Unfortunately this person was scammed. [Neither] Rihanna nor Roc Nation collected any money for this event."

Rihanna spent the majority of 2013 performing on her mammoth Diamonds world tour, which ran for 96 shows between March and November. The only African shows the We Found Love singer performed were in South Africa and Morocco.
