Did Justin Bieber call female fan 'beached whale'?

Justin Bieber has landed himself in another controversy by reportedly calling a bikini-clad young woman "beached whale" at a hotel in Australia.
The 19-year-old singer apparently made the uncharitable comments to the woman while she and her three friends were on a deck in bikinis at a hotel in Perth, reports news.Com.Au.
"One girl who was gorgeous looking, with long dark hair and would have been about a size 14," Helen Robinett, a hotel guest, who witnessed the interaction told the site.
"Justin looked over at her and said 'What are you, Hawaiian or something?' She said, 'No, I'm not.' Then he said, 'You look like a beached whale'... The girl said, 'Are you serious' and he said, 'You should go on The Biggest Loser'."

Robinett claimed the whole pool deck heard Bieber's rude comments. "Everyone heard. And there was silence. It was almost like his security were used to it."
Another guest, staying at the same hotel, confirmed hearing Bieber's comments.

"(He imitated) 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. I saw the girl and her friends leave, downcast. Bieber seemed to think he was funny, he was smiling and looking to his burly minders for their approval," the guest said.
Bieber was in the city as part of his world tour but the singer has been on a controversy making spree that includes fighting with his neighbours, sneaking out of a Brazilian brothel, illegally making a graffiti on a wall and allegedly spitting on fans from a hotel balcony.

The 'Baby' hitmaker, on his part, blames media for unnecessarily targeting him.
