Big Ang’s drug-dealing son dodged jail yesterday.

Over the objections of prosecutors, Anthony “AJ” D’Onofrio, the troubled offspring of busty, big-lipped Angela “Big Ang’’ Raiola — a star of VH1’s reality series “Mob Wives” — was sentenced only to rehab after pleading guilty to selling drugs in Brooklyn.

He could have faced up to 25 years in prison.

Prosecutor Jonathan Laskin had asked that D’Onofrio, 23, do at least some jail time for his role in a five-person narcotics ring that peddled oxycodone, marijuana and cocaine on the streets of Bensonhurst and Bay Ridge.

“These people should go to jail,’’ Laskin said to Brooklyn Supreme Court Justice Ann Ferdinand.

But defense lawyer Lance Lazzaro urged the judge to opt for rehab — and Ferdinand agreed.

“Clearly he has an addiction,’’ she said, adding to D’Onofrio: “If you successfully complete the drug treatment, you will not receive any jail sentence.”

Big Ang, of Staten Island, had given her druggie son a tongue-lashing in the most recent episode of “Mob Wives.”
