Sheen needs to help himself: Richie

LONDON - Socialite Nicole Richie has blasted Charlie Sheen for his recent drug troubles and says he is the only person who can get himself sober.

The 29-year-old has previously been to a rehab to be treated for drug dependence.

“I don’t think he should make it somebody else’s responsibility to keep him sober. If he wants (his sobriety) to last for a long time, it’s up to him. He’s an adult and he needs to take responsibility for his actions,” contactmusic.com reports her as saying.

Sheen was recently hospitalised with an apparent hernia after going on a 36-hour alcohol and cocaine binge.
