Donatella Versace has designs on staying sober after a trip to rehab last year.

The fashion guru tells the May issue of Vogue that her 18-year addiction to cocaine began at 32.

The murder of her brother Gianni Versace in 1997 prompted Donatella to abandon cocaine, but the sobriety didn't last.

She hit bottom after her women's show in March 2004.

Family and friends — including Elton John — used the 18th birthday party of Donatella's daughter, Allegra, in Italy to stage an intervention. She spent five weeks in rehab.

Now, she says, "I have all new habits. My day is totally different. . . . I don't want to feel that way again."
