Justin Bieber is alleged to have called one of his young fans a "beached whale" as she chatted with friends on the pool deck on Sunday at Perth, Australia's Hyatt Regency while on his current tour.

 Hotel guest Helen Robinett claimed she heard the 19-year-old singer yell out the abuse. She reported that four girls in bikinis were at the hotel's pool when the pop star looked over at one of them and reportedly said. "What are you, Hawaiian or something?" in reference to the girl's figure.

The girl, described as being "gorgeous looking" with long dark hair and "about a size 14," is said to have answered, "No, I'm not."

"Then he said 'You look like a beached whale,' " Robinett said she head Bieber say. "The girl said 'Are you serious' and he said 'You should go on The Biggest Loser' ...The whole pool deck heard him call this beautiful young girl a beached whale. Everyone heard. And there was silence. It was almost like his security were used to it."

Robinett said the young fan looked visibly upset and "deflated" after the abuse. Robinett's daughter, 21-year-old Gabrielle Blair, said the girl was "almost in tears" after the exchange, while Bieber's is said to have thought it was funny and was smiling.

Another guest from the hotel corroborated the story, adding that Bieber made a gesture with his hands to indicate a large belly. She said she arrived on the deck shortly before the incident began.

"I saw Bieber make a gesture with his hands to imitate a large belly as he spoke to the long haired girl and I heard him say something about The Biggest Loser and he was pointing at her - and I saw the girl and her friends leave, downcast," the woman said. "I also told her not to take any notice of him as she walked past us, I'm not sure if she heard me. Bieber seemed to think he was funny, he was smiling and looking to his burly minders for their approval."

Robinett reportedly made a formal complain to the hotel over the incident saying "They said the girl was OK and she was a Bieber fan. She may appear OK but I work in styling and fashion, I know how women view their bodies, what body image issues women have."

"That kind of comment can have a serious impact and repercussion. That's why I'm so upset about it," she added.

Bieber finished his tour in Perth over the weekend.
