Two music companies on Tuesday cancelled appearances by legendary tenor Placido Domingo over accusations that he sexually harassed multiple women — but the Metropolitan Opera said it would be awaiting the results of an investigation before making any calls.

The Met — where Domingo is scheduled to perform next month — said it would wait for a probe from the Los Angeles Opera, where Domingo, 78, has been the general director since 2003.

The opera superstar allegedly used his position at the LA Opera and at other companies to pressure women into sexual relationships, sometimes harming them professionally when they spurned his advances.

In a statement, the LA Opera said outside counsel would investigate the “concerning allegations” detailed in a bombshell Associated Press report published Tuesday.

The Met said it would wait for the results “before making any final decisions about Mr. Domingo’s future at the Met.”

The opera house held a $2,500-a-seat black-tie dinner in April for Domingo, who is set to play the title role in “Macbeth” in three shows there in September and October.

“We take accusations of sexual harassment and abuse of power with extreme seriousness,” the Met said in a statement, noting that “Mr. Domingo has never been in a position to influence casting decisions for anyone other than himself” at the Met.

Earlier on Tuesday the Philadelphia Orchestra announced it had rescinded an invitation for Domingo to sing at its opening-night gala on Sept. 18.

The San Francisco Opera said it would also scrub its sold-out Oct. 6 concert featuring Domingo.

The 50th anniversary concert had been billed as a “special one performance-only event” with “one of the most influential singing actors in the history of opera.”

Meanwhile, the Dallas Opera, where Domingo is scheduled to perform in March 2020, said it would be “awaiting further developments” before making any decisions.

The Salzburg Festival in Austria, where Domingo is scheduled to appear Aug. 31, said the singer would perform as planned.

The Met found itself in the middle of another scandal last year, when famed conductor James Levine was accused of sexual abuse by several male students. Levine, 75, was fired from the institution following an investigation into the allegations.
