Mayor Bill de Blasio does not seem thrilled by the prospect of being called to the stand at a former donor’s bribery trial.

“Asked and answered,” he snapped Thursday, when asked about his possible star turn in federal court.

“I’m not a lawyer,” he huffed at reporters during a Brooklyn press conference on traffic safety proposals.

Defense lawyers in the Brooklyn federal trial of former Nassau County Executive Ed Mangano said after opening statements Wednesday that they’re mulling calling the mayor to the stand.

Hizzoner would be grilled about the prosecution’s star witness, Harendra Singh, a crooked ex-restaurant owner who has sworn in court that he bribed de Blasio with tens of thousands in campaign contributions, and in return received special favors on a lease renewal for his Long Island City restaurant from City Hall.

Long Island federal Judge Joan Azrack is allowing defense lawyers wide latitude to cross-examine, and possibly impeach, Singh, telling them last month that they can ask about “everything he said about de Blasio and the de Blasio administration.”

De Blasio has countered that Singh was just angling for a good cooperation deal with the feds, and lied under oath “to save his own skin” by claiming he had the mayor in his pocket.
