Jenn Harley’s side hustles on Instagram are evaporating faster than her neighbors can call 911 on her … and it all stems from her domestic violence arrest.

A rep for Bellesa — a sex toy and porn company that caters to women — tells TMZ … the company’s cutting all ties with Ronnie Ortiz-Magro’s ex-GF, saying it’s appalled by the news she allegedly pointed a gun at her new BF, dropped the n-word and threatened to kill him.

Jenn’s partnership with Bellesa called for her to promote one of its sex toys on IG. For instance, on Mother’s Day weekend she posted, “Moms deserve to relax too!” … and alerted followers to hit her up for a free toy or gift card.

Her deal to pimp the famous Bentley Trike (stroller/bike) is also in jeopardy — a rep for Posh Baby and Kids, the distributor, says they’ve suspended the partnership, and will terminate Jenn’s contract if the allegations prove true.

Company prez Deepak Raghavan says “These incidents go against the values of our company. We don’t condone this behavior.”

As we reported … Jenn and her BF, Joseph Ambrosole, recently got into a heated argument in Vegas that included her leaving him stranded on the side of the road before things allegedly got so much worse when they got home.

According to the arrest report … Jenn pointed a gun and threatened to shoot Joseph while dropping the n-word. Cops say Joseph told them that Jenn said “I’ll shoot you na,” and “I’ll kill you right fing now,” before cocking the gun.

She was ultimately arrested and booked for domestic violence and assault with a deadly weapon.
