0927-justin-bieber-accusation-girl-TMZ-FACEBOOK-01Justin Bieber was at a recording studio in Australia Sunday night ... and a woman who was there claims she was drugged -- but other people at the studio say nothing like that happened.

In a social media post, the girl, an Australian model named Bailey Scarlett, says she was invited to the studio in Melbourne, Australia and poured herself a drink of vodka and lemonade. She claims she set the drink down and was chatting with some other girls there.

However, not long after that -- Scarlett says she began to feel woozy and her vision became blurred. She says she began to cry and Justin sat down with her to calm her down.

Law enforcement in Melbourne tells TMZ, they responded to a call at the location for a woman who "believed her drink had been spiked." She was then taken to a local hospital and advised to make an official report about the incident. We're told at this point she has not yet filed a report. 

Jimi Wyatt, who owns the recording studio, says they have reviewed footage from the event and claims Bailey's cup is visible the entire time -- he says her drink was never touched. Alex McDonnell, who organized the event, tells TMZ he believes the girl was having a panic attack. 

Bailey Scarlett has since made the post private claiming it was for legal reasons.
