And, odds are, you already feel like she's your friend.In her first book of essays, I Don't Know What You Know Me From, Greer writes about everything you would hope to hear from your best friend: how a midnight shopping trip to Walgreens can cure all; what it's like to wake up one day with stepchildren; and how she really feels about fans telling her that she's prettier in person. Yes, it's all herefrom the hilarious moments to the intimate confessions.But Judy Greer isn't just a regular friendshe's a celebrity friend. Want to know which celebs she's peed next to? Or what the Academy Awards are actually like? Or which hot actor gave her father a Harley-Davidson? Don't worry; Greer reveals all of that, too. You'll love her because, besides being laugh-out-loud funny, she makes us genuinely feel like she's one of us. Because even though she sometimes has a stylist and a makeup artist, she still wears (and hates!) Spanx. Because even after almost twenty years in Hollywood, she still hasn't figured everything outexcept that you should always wash your face before bed. Always.
