A judge lashed into the boyfriend of an alleged Manhattan cocaine delivery service client Wednesday for letting her snort away her beauty over the course of just three years.

Paul Samber, 32, and his girlfriend, Catherine Scott, bought blow from the dealers dozens of times from December to March 2015, prosecutors claim.

After a now-overweight and haggard-looking Scott was arraigned on the charges, the judge glanced at her 3-year-old Department of Motor Vehicles photo.

Then her boyfriend was hauled into the courtroom.

“Did someone show him the before-and-after photo of Miss Scott?” asked Justice Edward McLaughlin.

“I’ve known her since she was 13,” Samber replied.

“Maybe familiarity breeds blindness,” the judge said. “She’s deteriorating before your very eyes!”

Samber, a tech-support employee, looked as though he didn’t know whether to laugh or cry.

“She’s a makeup artist,” he whispered to his lawyer.

A source said the photo was just 3 years old.

Scott, also 32, who lives in Larchmont with Samber, was arrested Tuesday at the East Village salon where she works, said prosecutor Lucy Cutolo.

McLaughlin also had some choice words for Scott, who appeared in a sloppy T-shirt and baggy green hospital scrubs.

“People like Miss Scott are disregarding the law and doing their own thing because New York state and every other entity that outlaws drugs is just a party pooper [to them],” he said, weighing whether to set bail.

“She is without sufficient funds to make bail,” said her lawyer, Frank Rothman.

“But she has enough money for cocaine?” the judge asked.

“I think a lawyer costs more than a $250 special,” Rothman retorted.

The judge released the duo on their own recognizance and they left the courthouse holding hands.

Also charged was actor Jack Kesy, who plays a vampire in the FX series “The Strain.” He had his blow delivered to the trendy Lower East Side bar Pianos, according to court papers.

McGraw Hill senior manager Vadim Shalit, 32, was arrested Tuesday at his office at 55 Water St., where he often received his deliveries, prosecutors said. He allegedly blew about $5,000 in four months on coke.

“This prosecution demonstrates that whether you are allegedly directing a narcotics operation or are simply a paying customer, participation in illegal activity of this scale will not be tolerated,” said Manhattan DA Cyrus Vance Jr. “Today we are dismantling a sophisticated cocaine delivery operation top to bottom, from the three people charged under the state’s ‘Kingpin’ statute, to a dozen indicted sellers, as well as 10 separately charged buyers.”
