To her hard-partying pals in Miami, OnlyFans model Adriana Vieira was one of a small army of party girls in the sun-kissed fun spot.

But to alleged Brazilian fraud victims, the 31-year-old was a master scammer.

So far, Miami detectives are not suggesting mom-of-one Vieira — known on OnlyFans as Lady Rich Forever — was murdered but her criminal past adds more questions to the vexing mystery.

Vieira’s body was discovered floating near Key Biscayne on Sept. 21. She had reportedly gone swimming off a yacht owned by a prominent rapper. However, after the Brazilian was told that jellyfish were nearby, she ignored the warning and stayed in the water. The U.S. Coast Guard pulled her from the water about 10 minutes after she went under.

Now, according to the Daily Mail, Vieira and her hubby Roberto Tersário, and another couple, are accused in Brazil of having masterminded a multimillion-dollar scam that fleeced customers who paid for products that were never delivered.

Cops in Brazil closed in on the ring — which they said sold cellphones, TVs and other electronic products — in June 2020. More than 7,000 customers were burned in the Ponzi-like scam.

When the authorities finally shut the door, Vieira and Tersário were already resettling in South Florida. The twosome regularly posted snapshots of their bounty on social media.

Even though cops in Brazil reached out to their American counterparts, the pair were never arrested, the Daily Mail reported.

On the final night of her life, Vieira posted a photo of the luxe yacht party.

Cops said in a statement: “The group enjoyed food and alcoholic beverages. One of the patrons spotted jellyfish in the water and warned those who were in the water to get out. The decedent opted to stay in the water. She did several flips in the water and then dove underneath the surface headfirst. She never resurfaced.”

Vieira’s mom Lourdes thought the couple were into crooked dealings.

“I just suspected because no one gets rich overnight, no one leads such a luxurious life overnight,” she told Brazilian news station Record TV.

She added that her daughter did not speak English and her marriage was coming off the rails. Her husband had left her in Miami and returned to Brazil.

To put food on the table, Vieira began stripping at Miami clubs, working odd jobs and began selling raunchy content on OnlyFans.

Vieira’s Instagram account, which has 505,000 followers, contains modelling shots and photos of her 6-year-old son. He is being cared for by a babysitter until he can be flown back to Brazil to family.

A post on her account from Sept. 20 features a selfie with Tyga and a video of Lil Baby. Vieira walked the runway during Miami Swim Week in July 2023. In addition to modelling, the 31-year-old made music, Miami New Times reports.

Her official cause of death was listed as drowning. An autopsy revealed there were no drugs in her system.
