Canadian pop sensation Justin Bieber's mother has asked her son's fans to stop telling her that he makes them "horny".

The Beauty And A Beat hitmaker's mother Pattie Mallette, who has over 3.24 million followers on Twitter, told his fans, known as Beliebers, not to reveal their sexual fantasies.  

Earlier this month, during an interview with Vulture, Mallette talked about Bieber's growing up phase.

"I hope I've instilled enough values in Justin that he makes the right choices," she said. "Everyone goes through experimentation, whether in partying or another aspect of their life. They want to experience their own independence.

And for Britney and some of the others, having to make those mistakes judged by the entire world [is hard] ... I don't believe Justin will go down that road. And if he does, I think it would be short-lived," she added.

Meanwhile, the 20-year-old's family friend recently told InTouch magazine that his father, Jeremy Bieber, is partly to blame for his bizarre behaviour.

"Jeremy loves his kids more than anything, but he's enabling Justin's partying," Cory Bernier told the publication.

"When Justin was 18, I saw Jeremy give him [the prescription painkiller] Percocet. He said, 'Try one of these, son.' Justin liked the feeling and decided to go four-wheeling after taking it and ended up crashing into a pond," he added.
