Nearly 30 years after Sean “Diddy” Combs appeared as a musical guest on “Saturday Night Live,” Ana Gasteyer is calling him out.

The comedian labeled the embattled music mogul an “a–hole” for allegedly demanding “a totally closed set” during his 1998 appearance.

“He, of course, shut down the whole building,” Gasteyer, 57, said on the “Las Culturistas” podcast Wednesday. “You can tell the five a–holes in the six years that I was there when they would be like, ‘So-and-so is in the building, everybody stay in your dressing rooms!’”

While the “Mean Girls” actress called this behavior “applicable” for presidential candidates, she quipped, “Apart from that, it’s really my house.”

She also described her fellow cast member Will Ferrell making Combs, now 55, “very uncomfortable” during his rehearsal.

“They were like, ‘Wouldn’t it be so funny if Ron just went in?’” she recalled in the episode, referencing Ferrell’s character. “And he did.”

Gasteyer remembered, “He went on down the stairs and he marched right in. And I have the video from the control room where Sean Combs is rapping ‘Come With Me,’ and behind him Ron is just walking around looking really disoriented.

“It is the greatest thing that’s ever happened, because what a deserved person to have their ‘Kashmir’ moment interrupted by Ron,” she continued.

After clarifying that the rapper “really did not roll with” the interruption, the “Suburgatory” star blasted his “faux importance.”

She added, “Like, what’s gonna happen? You’re gonna walk into the studio and you’re gonna be like, ‘I’m in the studio. I work here.’”

Combs’ team has yet to respond to Page Six’s request for comment.

Ferrell, 57, previously spoke about the moment with Combs during a January 2020 interview with Vulture.

“Someone said, ‘Ron should go up onstage,’ and before everyone turned to see, I had sprinted out the door,” the actor said.

Combs’ behavior has come under scrutiny amid his recent legal troubles, from the Grammy winner’s September arrest to numerous sexual assault lawsuits against him.

Combs has repeatedly denied any wrongdoing.
