EXCLUSIVE
Rapper Pitbull torpedoed a famous Egyptian singer's music video -- after the singer spent hundreds of thousands to produce it -- and it's all Akon's fault ... this according to a new lawsuit.
Singer Tamer Hosny filed the suit against Akon ... claiming he paid the singer $300K for both him and Pitbull to sing on Tamer's new song "Arabian Knight."
Akon delivered the track -- but according to the lawsuit, in return for the $300K ... Akon and Pitbull were supposed to appear in the "Arabian Knight" music video ... but Pitbull was a no show.
Tamer claims Akon promised to deliver Pitbull for the shoot, so it's his fault and he's on the hook.
Tamer says it's double the disaster because he had to pay $100K for cameras and crew the day of the shoot ... all for nothing.
For some reason ... Pitbull was not sued.
Calls to Akon's camp weren't returned.
