Eleven more women have accused opera legend Plácido Domingo of sexual assault — about a month after an explosive report emerged in which several others claimed the married 78-year-old tenor made inappropriate advances toward them.

Among the new accusers is Angela Turner Wilson, who was cast as the second lead in Jules Massenet’s “Le Cid” during the Washington Opera’s 1999-2000 season.

Wilson, who was 28 at the time, told The Associated Press that she and Domingo were having their makeup done together one evening before a performance when the tenor — starring in the production — rose from his chair, stood behind her and allegedly put his hands on her shoulders.

Then he slipped his hands under her bra straps before reaching into her robe and grabbing her bare breasts, Wilson claimed.

“It hurt,” Wilson, now 48, told the outlet. “It was not gentle. He groped me hard.”

Domingo then walked away, leaving her mortified, she claimed.

Wilson also alleged that Domingo often invited her to his apartment to watch a video of a role he wanted her to sing, and to go to dinner one-on-one — a request that she said she answered with, “No, maestro.”

“I said that a lot,” she said. “I felt like if I put ‘maestro’ on it, it would still be respectful.”

Wilson also recalled a time that the tenor allegedly told her he needed a “kiss for strength” before a performance, as it was a “demanding role.”

She refused, reminding Domingo that she was married.

But he wouldn’t give up, she claimed.

“I said, ‘I’ll make you a deal. You can kiss my cheek,’” Wilson recalled. “So he kissed me on my cheek. And then he left.”

Wilson was the only new accuser who allowed her name to be used; others requested anonymity for fear of repercussions.

Several LA Opera costume department employees told the AP that Domingo’s alleged backstage behavior was no secret — one person even claimed her colleagues made a conscious effort to avoid sending women into fittings with the tenor as recently as the 2016-2017 season.

One former staffer alleged that Domingo once backed her up against a wall, grasped her hand and whispered into her ear, with her male boss in clear view.

She told the AP that someone should have called Domingo out for his alleged actions, “but it shouldn’t be the girl in the hallway on a headset trying to do her job.”

On Aug. 13, The Associated Press reported that eight singers and a dancer were sexually harassed by Domingo — two of them claiming they eventually gave in to his advances.

One of the accusers claimed Domingo left her $10 after one of the two times they had sex.

Domingo said at the time he believed all his “interactions and relationships were always welcomed and consensual,” that he would never “intentionally harm, offend, or embarrass anyone” — and that from now on he’d “hold [himself] to the highest standards.”

Nancy Seltzer, a spokeswoman for Domingo, issued a scathing response to the new allegations.

“The ongoing campaign by the AP to denigrate Plácido Domingo is not only inaccurate but unethical,” Seltzer said. “These new claims are riddled with inconsistencies and, as with the first story, in many ways, simply incorrect. Due to an ongoing investigation, we will not comment on specifics, but we strongly dispute the misleading picture that the AP is attempting to paint of Mr. Domingo.”

Wilson told the AP that she’d never spoken up before about her experiences with Domingo because she “felt that nobody else would say anything.”

But hearing other women speak up encouraged her to come forward.

“I know if I miss this opportunity and move on in silence, I will feel 20 times worse,” Wilson said. “It’s a big burden to carry around through your life. And every time another #MeToo story comes out, I go into a dark place, and I’m tired of it.”
