Cyndi Lauper’s son, caught with a loaded firearm during a shooting incident in Harlem, avoided a lengthy prison term on Friday by admitting to the weapon charge.

Declyn “Dex” Lauper, who pled guilty to second-degree criminal possession of a weapon in Manhattan Supreme Court, will undergo one year of interim probation. This stems from the shooting in Upper Manhattan on February 7, 2024, where his friend was injured in the leg.

Initially, Lauper faced the possibility of a seven-year prison sentence if found guilty in the firearms case.

The aspiring rapper, after accepting the plea deal, gave a thumbs up while sporting what he claimed to be a $10,000 Louis Vuitton jacket during his court appearance.

Under the plea agreement, Lauper is required to participate in a substance abuse treatment program and must remain arrest-free for a year.

Should he successfully complete the program without any infractions, Lauper will be eligible to plead to a lesser charge of criminal possession of a firearm, resulting in a three-year conditional discharge, as outlined by Judge Sara Litman.

The resolution comes more than two years after cops caught the 29-year-old with a loaded Glock .47 caliber handgun on 112th Street in Harlem, near where his 24-year-old pal had just been shot in the leg by a group of five gunmen, prosecutors have said.

Lauper — who denied that the gun was his — infamously tried wooing cops by name dropping his legendary pop-star mom after he was placed into custody.

“I grew up, my mom is Cyndi Lauper, Girls Just Want to Have Fun,” Lauper allegedly told a detective at the time, while also pleading for them to call his mom and life coach.

It was Lauper’s second conviction in Manhattan — coming after he took another plea to avoid jail time for stealing a Mercedes outside another rapper’s memorial in 2022.

Lauper’s attorney, Joe Tacopina, called the deal a “great resolution” for Lauper who is eager to put the case behind him and focus on his music future.

“He’s a great creative mind and has got a lot of things to do,” the high-profiled attorney said after the hearing. “This hanging over his head was a hindrance to that.”
