Model Bailey Scarlett believes that her drink was spiked while attending a party hosted by Justin Bieber at a recording studio in Melbourne, Australia on Saturday night.

Victoria state police confirmed to ET that they were called out to the establishment at around 11 p.m. local time after a woman alleged that she had been drugged. The woman then went to the hospital for medical treatment and was advised to make an official report to Richmond local police.

Scarlett, 18, reportedly posted to Facebook that she felt light-headed and suffered "blurred vision" after consuming alcohol at the party. The message has since been deleted.

"Last night, Bieber requested for a bunch of hot girls/models to go hang out with him in his recording studio down in Cremorne," Scarlett wrote on Sunday. "When I arrived, my phone was taken from me, [I] was introduced to Justin, [and] I was then told to pour myself a drink of vodka and lemonade."

Scarlett goes on to say that she put her cup down to chat with some of the other girls, did a shot with Bieber and then another drink was poured for her. After this, she says she became "incoherent."

"I burst into tears and began to feel unsafe," Scarlett wrote.

The model says the "What Do You Mean" singer and his "entourage" tried to calm her down, telling her that she was having a panic attack. "I was drifting in and out of consciousness, looking into Justin's eyes didn't do sh** to make me feel better."

Scarlett goes on to allege that the 21-year-old pop star "had a row" at her expense, saying that she had "never been given drugs," but had rather caught Bieber Fever.

"He is the most uninspiring person I have probably met in my life," she said of Bieber in her Facebook post.
