Cops arrived at the studio in Melbourne to tend to Bailey Scarlett, who believed her vodka and lemonade had been spiked, and she was taken to a nearby hospital.

Scarlett opened up about the incident on Instagram.com, claiming she felt dizzy and her vision was blurred after ingesting the drink. She also reveals that Bieber comforted her as she began to cry, but she has since made the post private.

The owner of the studio, Jimi Wyatt, has told TMZ.com he reviewed surveillance footage and believes her drink was never touched, while Alex MCDonnell, who organised the event, claims Scarlett suffered a panic attack.

Scarlett had not filed a police report as WENN went to press.
