VIDEO: Husband’s arson destroyed Bronx salon owned by Jenny Bui, creator of Cardi B’s famed nail style: FDNY (EXCLUSIVE)

The fire that destroyed a Bronx salon about to be opened by stylist Jenny Bui, who rocketed to fame when she created the viral “stiletto nails” look for rapper Cardi B, was arson — and Bui’s disgruntled husband sparked the inferno — FDNY officials said Wednesday.

Bui, 54, apparently unaware of her husband’s alleged responsibility for the blaze, launched a GoFundMe in the wake of the incident.

“The current loss I’m going through has been devastating,” the self-described “Queen of Bling” told her 1.3 million Instagram followers the day after the fire. “I didn’t have the chance to take out insurance for the store because of a current family member in critical condition and was so focused on family that I didn’t have time to prepare for something as unfortunate as this.”

Her husband, Nguyen Bui, tasked with refurbishing the space, told investigators he drunkenly set the blaze while his wife was “driving him crazy” over meeting the deadline for the shop’s grand opening later this week, a law enforcement source said.

He denied his actions were intentional.

There’s no indication that Jenny Bui played a role in the arson, according to law enforcement officials.

“When we questioned him, (he) actually seemed very concerned with his wife finding out that he had done it,” a law enforcement source told the Daily News. “He was more scared of that than going to Central Booking.”

Surveillance video obtained by the Daily News shows the arsonist using a lighter to set napkins on fire and tossing them onto a pile of cardboard boxes around 4:50 a.m., sparking the Sept. 28 blaze. By 5:30 a.m., the shop was engulfed in flames.

But the day of the fire, he actually rushed to the scene with his wife in the same car, according to the owner of a nearby business.

“He was like this — ‘Oh, my god! My place is burnt!’ He acted like he’s crying,” the business owner told The News. “He said, ‘Oh, my God, who did it? Who made my place fire?’ He said, ‘Maybe jealous people.’”

FDNY fire marshals arrested Nguyen Bui, 48, on Oct. 11. Two firefighters were injured battling the blaze on E. Tremont Ave. in Throggs Neck, which took about two hours to put out.

When questioned, Nguyen Bui said he snapped under the pressure to meet his wife’s deadline, the law enforcement source said.

“He had been painting all day and drinking and he said he didn’t mean to start the fire,” the source said. “He’s just lucky the fire didn’t go to any other stores or hurt anyone.”

Nguyen and Jenny Bui’s attorney asserts the surveillance video “doesn’t show the entire story.”

“He worked through the night and was under extreme stress to make the grand opening,” Darnell Crosland told the Daily News on Wednesday. “He’d been drinking a little bit to push through. He had a meltdown.”

Jenny Bui, who survived the Khmer Rouge regime while growing up in Cambodia, had just taken occupancy of the shop a few days before the fire.

“She forgives him,” Crosland said of Jenny Bui. “He’s a good husband. He was under extreme pressure.

Crosland insisted the arson was not “an insurance scam” and noted Nguyen Bui is currently undergoing court-mandated psychiatry and substance abuse treatment.

“The fire could easily get between the spaces and there’s a common cockloft where the fire could spread,” FDNY Chief Fire Marshal Daniel Flynn said Wednesday. “The firefighters did an excellent job extinguishing the fire and limiting it to the damage that was caused. It could have been a lot worse.”

Bronx prosecutors charged Nguyen with arson and criminal mischief. He was released without bail after a brief arraignment hearing in Bronx Criminal Court. He’s due back in court Nov. 13.

“To say, ‘I didn’t mean to set the fire’ is misleading,” Flynn said. “From the video, it’s clear he obviously intended to set the fire and did so.”

Fire marshals managed to revive the badly damaged security DVR and pull the video directly from the hard drive.

“It was really great work done by the marshals,” Flynn said. “Thank God for video, it makes our life a lot easier.”

Jenny Bui, a mother of five, estimated that about $100,000 worth of fake nails and manicure materials was destroyed in the fire. She said she hadn’t transferred her insurance from her shop in the Fordham section of the Bronx to her new location.

“When I saw this, my reaction was that I was about to pass out,” Jenny Bui told News 12 Bronx looking over the charred remains of her shop. “Luckily, I have my neighbors who held me and they said, ‘It’s OK, Jenny. We’re all going to help you.'”

Her GoFundMe has raised over $8,000.

“I am so heartbroken and sad,” she wrote on the GoFundMe post. “Everything I worked hard for all taken away.”

Some of her neighbors weren’t too broken up over Bui’s loss and had few kind words for her husband.

“She makes all the money,” one neighbor said. “He sits around fixing cars waiting for her to make that money. Now she’s asking for money to rebuild, but she acts like she’s a millionaire.”

Cardi B was in Queens Criminal Court in January asking for more time to complete the community service she was sentenced to in connection with a strip club assault. The Bronx-born chart topper pleaded guilty for her role in a bottle-throwing attack at the Angels Strip Club in College Point in August 2018.
