People reports that tennis legend Andre Agassi reveals past crystal meth usage in the late 1990s in his new memoir entitled Open. “I can’t speak to addiction, but a lot of people would say that if you’re using anything as an escape, you have a problem,” he told People. In addition to drug use, Open describes his hair loss, troubled marriage to Brooke Shields and eventually meeting his current wife Steffi Graf. Random House publishes the book on Nov. 9; excerpts appear in this week’s People and Sports Illustrated.
