Boxer Floyd "Money" Mayweather Jr is being sued for allegedly stealing a rapper who was already under contract.

Floyd signed Philadelphia rapper Freck Billionaire to his Philthy Rich Records imprint in 2008.

At the time Floyd says he asked Freck if he was under any type of recording contract with anyone else and was told no.

Enter Just For You Entertainment, a Long Island Management firm that is suing Floyd for interfering with their previous relationship with Freck.

Just For You filed the lawsuit in November 2009 and because Floyd hasn't responded they are seeking a default judgement of $155,000 which will cover their out of pocket expenses on Freck. Including studio time and living expenses for the rapper, as well as child support the rap star owed.

They also seek $600,000 in additional damages.

There's no love lost between Floyd and Freck who have been sending shots at each other via the media.

Floyd spoke to Allhiphop in 2009 and had this to say:

"We were working with an artist named Freck Billionaire. When he came aboard we asked if he had any contracts and he said no. Come to find out he was signed with somebody. The guy was trying to sue us and Freck stole one of our watches and left. So we’ve been looking for Freck Billionaire but he’s been ducking and dodging us. He stole a diamond watch and left."

In response Freck, who is a part of Fabolous' Street Fam recorded a diss track titled "39-1" and told AllHipHop.

"Since you really at the bottom of your heart don't wanna see anyone around you with anything, I'll send a courier to you with my watch. Maybe you can use it to lure in your next victim,"
