The In Da Club hitmaker, real name Curtis Jackson, is heading to trial next month (Jun15) to defend himself against claims he posted footage of a bedroom romp between Ross' ex, Lastonia Leviston, and her then-boyfriend, Maurice Murray, online in 2009.

50 Cent allegedly edited the video to embarrass rap rival Ross, blurring Murray's face and inserting an image of himself into the footage.

Leviston is demanding damages for emotional distress and unauthorised use of her name and image, but 50 Cent is now claiming he was not responsible for the leak and revealing Ross, real name William Roberts, allegedly made his plans to expose Leviston in a radio interview a day before the explicit video surfaced on the web.

50 Cent claims he only shared a link to the adult film on his site.

Ross' lawyer is now hitting back at Jackson's allegations, insisting his claims hold no basis because the Hustlin' hitmaker was not named in the original suit.

In a statement to, Xavier Donaldson writes, "The recent lawsuit filed by Curtis Jackson against Mr. William Roberts is clearly another attempt to draw attention to his descending entertainment career and one of several desperate, last minute attempts he's made to avoid and deflect legal and financial responsibility for his own actions related to the pending New York City civil trial, in which he's a defendant."

He continues, "The New York City lawsuit was filed against Curtis Jackson five years ago. Mr. Roberts was neither named as a defendant nor legally joined by Mr. Jackson in that suit. If and/or when Mr. Jackson properly serves Mr. Roberts, we will aggressively address and defend against these frivolous and futile claims."
