Nicki Minaj came all the way to China to perform – but then never went onstage.

The celebrity rapper was scheduled to perform in Shanghai on Sunday as part of the Djakarta Warehouse Project (DWP), a world-renowned dance festival that originated in Bali. But when it came time for her set, she never appeared, Shanghaiist reported Monday.

Neither Minaj nor DWP have issued a statement. But the Shanghaiist theorizes it may all have been a scam. According to the popular blog, the event’s website put up a notice just days before the festival, reading: “The event rumored to take place in Shanghai on 17th & 18th of November 2018 is an unauthorized use of DWP trademark. DWP as a brand has no association with the event. The alleged lineup artwork of DWP China, which has been circulating online, is unauthorized.”

Rumors are swirling online about the possible reasons for Minaj’s last-minute cancelation: Some say the venue was smaller than Minaj was told, the Shanghaiist wrote. None of this, however, has been confirmed.
