Sean “Diddy” Combs has been hit by another damning lawsuit, this time from a model who claimed he drugged her and then forced her to perform oral s3x on him during a visit to his NYC studio two decades ago when she was 22.

Crystal McKinney claims the rapper plied her with alcohol and possibly laced marijuana during the 2003 encounter, then brought her to a bathroom and forced her to her knees, demanding she “Suck it,” according to the suit obtained by TMZ.

McKinney alleged that when she refused to comply, Combs grabbed her head and forced her to perform oral s3x on him.

She then lost consciousness and woke in a taxi to realize she’d been assaulted, the suit read, although it remains unclear whether she meant there was an additional assault beyond the oral encounter.

The suit is just the latest damning allegation to be made against the hip-hop mogul in recent months.

Since his ex-girlfriend Cassie Ventura accused Combs of rape and abuse back in November, he’s been hit by six lawsuits alleging abuse, including the latest from McKinney.

The pair allegedly met during a Men’s Fashion Week event at Cipriani, where he invited her to join him at his studio afterward.

There, McKinney alleged she and Combs drank some expensive booze with friends, and then began passing joints around the group, TMZ reported.

The weed was “very powerful,” so much so that she began to feel like she was floating and feared it had been laced with another drug.

Combs then made her go to the bathroom, where he forced himself on her, McKinney alleged in the suit.

After the incident, McKinney claimed she was blackballed from modeling and became so depressed she tried to kill herself in 2004.

Following the deluge of allegations against Combs, McKinney said she decided to come forward because she “knew she had a moral obligation to speak up,” according to TMZ.

Combs’ mansions in Florida and California were raided in April by a Department of Homeland Security team dealing in human trafficking after allegations emerged against him.

Despite initially denying all allegations against him, Combs on Sunday apologized after footage emerged of him viciously beating Ventura in a hotel hallway in 2016.

In that clip, Ventura was seen trying to get into an elevator before Combs emerged around a corner clad only in a towel, grabbed her by the neck and threw her to the ground.

He then kicked her several times, before pulling her from the ground and throwing her back around the corner.

Later he was seen hurling objects at Ventura as he aggressively yelled at her.

The footage lined up with a vivid description of the assault she detailed in her November filing against Combs — which was settled out of court with the rapper maintaining his innocence.

In the filing, Ventura said she was wearing a hooded sweatshirt as she tried to escape to conceal a black eye Combs had given her.

On Sunday, Combs issued an apology video, claiming he had hit “rock bottom” in the footage and that he’d spent the years since seeking therapy to be a better person.

Ventura’s lawyers dismissed the apology, saying Combs did nothing but talk about himself in it.
