Drew Barrymore gives stern advice to young stars

Actress Drew Barrymore has urged troubled young stars like Amy Winehouse and Britney Spears to "pull themselves together".

The Tinseltown beauty - who entered rehab for the first time when she was just 13-years-old, believes the only way to beat your drink and drug demons is to do it for yourself.

The 'Charlie's Angels' star - who started drinking alcohol when she was nine and smoking marijuana when she was 10, said: "If you don't pull it together for yourself, no one else will. That's coming from a person who had to try it all and who still loves to have a good time."

The 32-year-old star - who shot to fame playing 'Gertie' in the smash hit Steven Spielberg film 'E.T. the Extra-Terrestrial' when she was seven - also insists she never let her personal problems affect her work.

She added to Vogue magazine: "I do believe in 'Work hard, play hard,' but 'Work hard' always comes first, and it did even when I was wild and young."

Drew has seemingly put her wild days behind her and has been dating actor Justin Long for six months.

She was previously married twice - to Welsh bartender Jeremy Thomas and US comedian Tom Green.

Drew had a long-term relationship with Strokes drummer Fabrizio Moretti, but the pair split in January 2007.
