The In Da Club hitmaker claims he hired Andrew Jameson for $270,000 (£168,750) to set up various business and TV deals for him, but after his contract expired, he allegedly pitched a new reality project to bosses at America's E! network about a "young white girl" working at 50 Cent's G-Unit Records.

He reportedly signed a deal with E! chiefs on 50 Cent's behalf for The Unit, but when the rapper found out, he blasted the idea as "highly offensive".

He then had to back out of the deal with E!, which he claims "severely damaged" his relationship with the network's parent company, NBCUniversal.

50 Cent, who is currently embroiled in his own bankruptcy proceedings, is now demanding Jameson pay him damages of more than $800,000 (£500,000) for the mess.

However, Jameson's lawyer, Eric George, has blasted the allegations.

George quips to TMZ.com, "His claims aren't worth 50 cents. In fact, Andrew is the one owed money - several months of unpaid salary... and he's in arbitration to get it."

50 Cent filed for bankruptcy in July (15).
