Sean 'Diddy' Combs' youngest son Christian 'King', 25, is sued for sexual assaulting a woman during a 2022 yacht party

As Sean 'Diddy' Combs' ongoing sex-trafficking investigation continues to unfold, his youngest son is named in a new lawsuit.

Christian 'King' Combs, 25, has been sued for sexually assaulting Grace O'Marcaigh, a woman working on a yacht his father chartered in the summer of 2022, according to court documents obtained by Us Weekly. 

Filed Thursday in Los Angeles County Superior Court, the lawsuit also accuses King of sexual harassment and infliction of emotional distress.

Diddy is also accused of aiding and abetting his son, named in the lawsuit for premises liability for chartering the boat. 

O'Marcaigh claimed that the trip was 'sold as a wholesome family excursion' but became a 'hedonistic environment.'

The alleged event took place in late December of that year, shortly before Diddy hosted a star-studded yacht party on New Year's Eve. 

According to TMZ, O'Marcaigh alleges that King tried to kiss and grope her after giving her a shot of liquor she suspects was spiked.

The outlet reported that O'Marcaigh also has audio recordings of herself allegedly turning down his advances in the yacht's studio and trying to get away from him. 

Afterward, King allegedly attempted to force O'Marcaigh to perform oral sex on him.

She included photos of bruises on her arm, which she says she got during the altercation while fighting him off and escaping.

Aaron Dyer, a lawyer on Diddy and King's defense team responded to the lawsuit in a statement to Us.

'We have not seen this woman’s claim but I'm sure we can expect the same kind of manufactured lies we've come to expect from Tyrone Blackburn and his clients, just as we saw in Rodney Jones' lawsuit – which has yet to be served,' said Dyer.

'He was just slapped by a federal judge in New York earlier this week for his "pattern of behavior" in "improperly [filing] cases in federal court to garner media attention, embarrass defendants with salacious allegations, and pressure defendants to settle quickly,"' he continued.

'Two days after he was referred to the disciplinary committee in the Southern District of New York, it's interesting he chose to file a new suit in California. 

'This is just another page from that same playbook, as we learned of this lawsuit the same way anyone hears about Mr. Blackburn's filings: through the media,' Dyer added.

After King and brother Justin, 30, were arrested last month during raids on their father's Los Angeles and Miami homes, they have hired attorney Jeffrey Lichtman, accusing investigators of 'excessive use of force' during the arrest at the Holmby Hills, Los Angeles mansion.

King also broke his silence on Snapchat after the arrest, writing, 'Stop with the [blue cap emoji],' which translates to 'Stop lying.'

Diddy is the subject of mounting sexual harassment and rape lawsuits, recently culminating in Homeland Security Investigations raiding his homes, where they were seen removing boxes and bags of evidence.
