The girlfriend of a disgraced securities broker was busted for torching his clothes because she suspected him of straying, court papers allege.

Ardita Dajbabic had a spat with lover Enver Alijaj — who came under fire in 2015 for allegedly making excessively risky trades with his clients’ multimillion-dollar accounts.

Cops responded in April to reports of a fire at Alijaj’s pad at 75 Wall St., a condo building that houses the luxury Andaz Hotel on its lower floors.

“I thought he was cheating on me so I lit his clothes on fire,” Dajbabic allegedly admitted. Alijaj’s 1-year-old son was present for the fiery outburst last April 22, authorities said.

Dajbabic, 25, was hit with reckless endangerment, endangering the welfare of a child and arson raps.

After rejecting a plea deal last week, Dajbabic strutted out of Manhattan Criminal Court teetering on a pair of Louboutin stilettos.

Alijaj, 42, who came under scrutiny for his practices while a broker for JHS Capital, has listed his luxury condo for $1,595,000 on streeteasy.com.

By 2015, Alijaj had been hit with 14 client complaints alleging $16 million in damages for the trades that netted him big commission fees, according to the Wall Street Journal.

FINRA records show that he was barred from working as a broker in 2014.

Dajbabic’s defense lawyer, James Froccaro, declined to comment. Alijaj didn’t immediately respond to requests for comment.
