Russell Brand has said that young teen stars should take drugs to “weed out” the worst stars.

Speaking to Rolling Stone he joked that the “Darwinian” method could be usedon Disney popsters and singers like Justin Bieber.

Russ’ said: “We would be spared their awful music. The top of the hit parade would look very different if teenyboppers were exposed to heroin.

“It would weed a lot of them out.”

The controversial comic continued, comparing Bieber to Pink Floyd star Syd Barrett.

"I don't think Justin Bieber could handle Syd Barrett's habit” said Brand.

“You're just not allowed into the studio until you first have had drug-addiction issues. It separates the men from the boys.”
