Uh-oh. It looks like Justin Bieber's just chipped (hacked) away at another gleaming layer of his floppy-haired sweet boy image.

On Friday, the Baby singer was caught trying to sneak out of popular Brazilian "brothel" Centaurus with the help of his burly minders who covered him in a white sheet.

The 19-year-old then jumped into the back of a waiting car and was joined by two females from the club, claim reports.

An insider says Justin believed he was a guest at a private club.

According to one website, Centaurus is listed as the "Top 4th" brothel in the world, and says "$210 buys you 40 minutes with any girl".

Although the controversial singer is draped in the sheet, part of his well-known wrist tattoo is on display.

Justin, who's in Brazil for a string of gigs, also apparently got chucked out of his hotel - the swanky Copacabana Palace in Southern Rio - but a source says he voluntarily left because the gathering hordes of fans were creating a "security issue".

This isn't the first saucy trip that's landed Bieber in the headlines. Two weeks ago, he was was pictured flashing large wads of cash in a Texas strip club.

A rather star-struck dancer from the club then posted a message on Twitter, which the whole world (anyone who cared) later saw.

"He touched my Ass and I Almost fainted, she wrote. Shortly followed by, "He Was Like Its Real!!"

With his new bulging biceps and six-pack, wispy moustaches and latest x-rated trips, we think he's doing a bloomin' great job at dusting off his old image.

We have contacted a representative for Justin for comment.
