OnlyFans creator Adva Lavie, also known as Mia Ventura, is under investigation for allegedly drugging her former fiancé, Stephen Cloobeck, with ketamine. This development comes amid ongoing legal proceedings where Lavie faces multiple felony charges, including theft and burglary.

Investigation Details and Arrest

A warrant filed by a Los Angeles Police Department (LAPD) detective in August 2026 has brought new details to light regarding the case against Adva Lavie. The warrant indicates that Beverly Hills Police Department (BHPD) Detective Steve Own observed Lavie at Azur restaurant over the summer, taking selfies on the patio. Detective Own was already familiar with Lavie because he had been investigating whether she was drugging Stephen Cloobeck with ketamine.

Lavie was arrested on July 28. At the time of her apprehension, authorities discovered she was not wearing a court-ordered ankle monitor, a violation of her release conditions. She was subsequently denied bail and is currently incarcerated pending trial. The LAPD detective’s warrant requested a search of Lavie’s mobile phone.

Stephen Cloobeck, a wealthy real estate developer who briefly ran for governor of California last year, previously filed a report with the BHPD. The warrant affidavit does not specify the circumstances behind this report or what prompted the drugging allegation. Cloobeck announced over the summer that he called off his wedding to Lavie.

Related Legal Troubles for Lavie and Cloobeck

Adva Lavie, 29, faces trial in Los Angeles County on two counts of grand theft and two counts of first-degree residential burglary. She has pleaded not guilty to these charges and faces at least 11 years in prison if found guilty. In addition to these charges, Lavie was arrested on a felony warrant for theft filed by the Indio Police Department. This warrant relates to a high-value robbery case that occurred at an Airbnb within Indio city limits during the 2025 run of the Coachella music festival.

Stephen Cloobeck also faces legal issues tied to his previous relationship with Lavie. He was arrested in May and pleaded not guilty last month to felony witness tampering charges, reportedly connected to a case against Lavie.

In September, Lavie’s mental competency was called into question by her defense attorney. During a courtroom appearance in late August, Lavie was observed dressed in a blue jail jumpsuit, crying, limping, and making what were described as absurd statements during a hearing.

Background and Allegations

Court filings provide insight into some of the alleged incidents. The warrant highlights an event involving a former friend of Lavie who attended a dinner party at Stephen Cloobeck’s residence where Lavie was also present. Following the gathering, the guest reported that her purse had been moved and her engagement ring was missing. When the victim approached Lavie for assistance in locating the jewelry, Lavie reportedly became defensive and dismissed the woman as a “drunk.”

Adva Lavie has been known as Mia Ventura and has touted herself as the "first" top OnlyFans model of Israeli origin. She was featured as the July 2023 Penthouse Pet of the Month.
