US make-up mogul Jeffree Star has revealed that $2.5m (£1.9m) of stock, including unreleased products, was stolen from his company's warehouse.
Star shared details of the theft in a YouTube video posted on Wednesday.
In the clip he reveals it happened in the early hours of 16 March - alleging a team of "professionals" broke into the Los Angeles facility.
Star has said that local law enforcement and the FBI are investigating the crime.
The 33-year-old said he and investigators believe the products were stolen to be sold onto the black market.
Police have not yet commented publicly on the case.
Star revealed the crime after an unreleased concealer product, which had been under development for a year, began to appear on social media marketplace sites over the weekend.
Fans of the brand had expressed their confusion about the leak.
I never knew I’d be spending my Monday night with the FBI tracking down black market makeup sellers.
