A popular fashion influencer has mysteriously vanished in Mexico, just hours after sharing a chilling video of herself crying in clown make-up.

Flor Marian Izaguirre Pineda, better known as Marian Izaguirre, was last seen around 6pm on Monday, September 1, in the city of Uruapan, located west of Mexico City.

The 23-year-old social media star, who commands an audience of nearly 4 million followers on TikTok, has not been heard from since.

The day before her disappearance, Izaguirre posted a haunting video to her Instagram and TikTok accounts.

In the unsettling clip, she is seen sitting in what appears to be a park, with her face painted like a clown while tearfully lip-syncing to the emotional song 'Why Are You Leaving?'
