NEW YORK, USA (AP) – Producer and musician Sean “Diddy” Combs was accused in a lawsuit Thursday of subjecting R&B singer Cassie to a years-long relationship that included beatings and rape.

According to CNN, the singer, whose real name is Casandra Ventura, is demanding US$30 million in compensation.

Ventura, alleges in the suit filed against the producer and music mogul in New York federal court that Combs brought her into his “ostentatious, fast-paced, and drug-fuelled lifestyle” not long after she met him and signed to his label when she was 19 and he was 37 in 2005.

Combs’ attorney Ben Brafman did not immediately respond to an e-mail seeking comment. In a statement to The New York Times, he said Combs denies the allegations.

Ventura, now 37 herself, said Combs, now 54, began the pattern of abuse soon after. The suit alleges he subjected her to savage beatings, plied her with drugs, and forced her to have sex with other men while he masturbated and filmed them.
