Book You're Most Embaressed to Say You Liked

I went through this weird phase after finishing my Masters where I wanted to read fluff and it was the era of chick lit.  One of the books that I found myself enjoying (but no longer would) is Confessions of a Shopaholic.  While the main character was somewhat endearing, there was really just no substance to the book.  For me, this book is now too light for even a beach read!
