THE FATBOY SHOW : Diddy accuser's ex-boyfriend says she offered a 'bribe' to back rape allegations.

The ex-boyfriend of Thalia Graves - who has sued Sean 'Diddy' Combs - is accusing her of attempting to bribe him with $3 million if he vouched for the claims she made against the rap impresario.

Graves on September 24 filed a lawsuit in New York federal court, claiming the music mogul and his head of security Joseph Sherman raped her and recorded it on video at his New York recording studio in 2001.

Graves said her ex-boyfriend told her late last year - following the lawsuit raised by Combs' ex Cassie, which was settled in a day -informed her that the rapper had recorded the incident, shown it to others and sold it as pornography.
