Hey, they’re supposed to be the good guys.

A Queens prosecutor and her boyfriend, an NYPD detective, were busted yesterday for fighting with cops trying to keep their verbal battle from turning physical, authorities said.

Off-duty Detective Samir Gonsalves, 34, and Assistant DA Jacqueline Rizk were screaming at each other on Steinway Street in Astoria at 10:15 a.m. when cops, alerted by a cabby, arrived.

The on-duty officers attempted to calm down the brawling lovebirds.

Gonsalves pushed one of the officers and was wrestled to the ground, cops said. While his colleagues were cuffing Gonsalves, of Brooklyn’s 88th Precinct, Rizk allegedly jumped on a cop’s back.

A source said the two are romantically involved and appeared to have been drinking.

Both face charges including resisting arrest, and were released without bail. Gonsalves was suspended and Rizk was placed on leave.
