Britney Spears doles out advice to Justin Bieber

Britney Spears reportedly had to "talk some sense" into Justin Bieber about his bad behaviour.

Spears, who also had her fair share of negative press in her initial days in the past, was apparently asked by Bieber's team to impart her knowledge to the troubled teen, the Sun reported.

A source told the publication that Spears warned him of the slippery slope that can easily lead to rehab or even death among young pop stars.
