NEW YORK(AP) Andre Agassi tells People magazine he used crystal meth periodically for ``a year or so.''
In his upcoming autobiography, Agassi admits he used crystal meth in 1997 and failed a drug test - a result he says was thrown out after he lied by saying he ``unwittingly'' took the substance.
The eight-time Grand Slam champion tells People that he felt it necessary to be as candid as possible in the memoir. New excerpts published Friday reveal Agassi wore a hairpiece that nearly fell off at the 1990 French Open, became jealous during ex-wife Brooke Shields' appearance on ``Friends,'' and how Shields put a photo of Steffi Graf - now married to Agassi - on the fridge for motivation to get in better shape before their wedding.
