Justin Bieber's former housekeeper says he will “become the next Michael Jackson” if he isn't careful.

Tatiana Voziouk has claimed the singer's drug use is making him into a “zombie”, and she is constantly “terrified” he will end up dead, like the 'Thriller' hitmaker who passed away in 2009.

She told the Sunday People newspaper: “The drugs and hangers-on are turning Justin into a zombie.

“I'm terrified he'll become the next Michael Jackson. If he doesn't act now I will hear one day that he has passed away.

“It is heartbreaking. I have decided to speak out now as I care for him.”

Meanwhile, according to reports in The Sun on Sunday newspaper, the 'Beauty and a Beat' singer - who was charged with drink driving, resisting arrest and drag racing in Miami in the early hours of Thursday morning (23.01.14) - “smokes 12 bongs a day”.

A source said: “Weed plays a huge part in Justin's life. He smokes 12 bongs a day and can spend £5 000 a week.”

They also suggested the “out of control” had to “see sense” while he can still help himself.

The insider added: “Justin thinks he is invincible. He's out of control. Hopefully he'll see sense before it's too late.” - Bang Showbiz
