Former Metropolitan Opera conductor James Levine filed a lawsuit against his former bosses on Thursday, claiming he was unjustly fired in the wake of sex claims.

Levine, who is seeking $5.8 million in damages, said baseless allegations of sexual misconduct cost him his job and reputation.

The famed conductor was dumped on Monday.

The Met launched an investigation against Levine and suspended him back in December after The Post and Times reported allegations of sexual misconduct against him, involving boys from decades ago.

Levine has denied those claims and he’s not been criminally charged.

Bettina “Betsy” Plevan, a lawyer for the Met, said Levine’s lawsuit is “riddled with untruths.”
