Diddy is being sued by ex-Making the Band member Dawn Richard, who claims he sexually abused her

A new lawsuit has been filed against Sean “Diddy” Combs by a woman who claims the hip-hop artist and music manager sexually abused her – and that she witnessed him allegedly hitting her ex-girlfriend Cassie Ventura, according to a new report.

Singer Dawn Richard, a contestant on Combs' MTV show “Making The Band” in 2004, claimed the music mogul once broke into her dressing room and started groping her breasts and butt, TMZ reports..

In another incident, Richard said, Combs asked her to come to his home in Miami, where he greeted her wearing only his underwear.

When she asked him to get dressed, Diddy refused and screamed, “This is my damn house!” the lawsuit states.

In addition to the alleged sexually inappropriate behavior, Richard accused Combs of being a violent man who once forced them to rehearse for 48 hours at a time without sleep.

The Grammy winner also once locked her in a car for two hours while she screamed for help, she claimed in the lawsuit.

During the incident, Richard's father traveled from Baltimore to New York to rescue his daughter and confront Combs, threatening to report him to the police, the lawsuit says.

Combs is said to have warned Richard's father that he should consider his daughter's career when calling the police.

The lawsuit also reflects the abuse Combs allegedly inflicted on Ventura, for which he publicly apologized in 2016 after footage of the incident surfaced earlier this year.

Richard is said to have been present at Combs' first meeting with Ventura in 2006 and described his behavior as “predatory.”

In 2009, Richard claims she saw Combs, under the influence of drugs, throw Ventura against a wall, choke her and drag her up a flight of stairs in his Los Angeles home.

The singer also claimed that Combs once hurled a scalding hot pan of eggs at Ventura and screamed, “I asked you for my shit; I can't stand you, bitch, you never do it right!”

In another incident, Combs allegedly punched Ventura in the face and attempted to strangle her, the lawsuit says.

When Richard and other women came together to support Ventura's decision to leave Combs, the Grammy winner allegedly attacked and threatened them, the lawsuit says.

“You bitches don't interfere in my relationship,” Combs is said to have screamed. “Don't tell my bitch about this. [Cassie] what she has to do.

“…Just make money and shut up…I destroy artists…I put careers on hold…You might be missed…You bitches want to die today,” he added.

The lawsuit also alleges that Combs also beat another ex-girlfriend, Kim Porter, because she saw the woman running out of Combs' music studio in 2005, crying and with a bruised face.

Combs has not yet responded to the latest allegations against him.
