A man named John Jacobs filed the suit against the duo claiming J.Lo and Marc ripped off his idea for the reality show after he contacted them about it a few years ago, according to TMZ.
John claims he contacted Marc's Marc Anthony Productions and the "Hit the Floor" crooner's Nuyorican Productions about his show idea, Miami Beach: the Game in 2007 and 2008, in which two well-known Latino celebrities traveled in search of the next big superstar.
He went on to say both J.Lo and Marc's companies expressed interest in his project at first and then started ignoring his phone calls.
When he saw ads for Q'Viva, which aired last year, John said he was "blown away" by the similarities to the concept he had pitched.
"They were so similar that they were twins," he went on.
After supposedly trying to contact both companies and getting no response, he filed the lawsuit.
Neither Marc's company or J.Lo's company have commented on the suit.
