You know Judy Greer, right? Maybe from The Wedding Planner, 13 Going on 30, Carrie, Arrested Development, or The Descendants . Yes, you totally recognize her. 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 here--from the hilarious moments to the 
intimate confessions.

But Judy Greer isn't just a regular friend--she'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 out--except that you should always wash your face before bed. Always.
