Lauren Conrad is coming out with a beauty book.

In it, I'll provide my personal insights, instructions and tips to keep you looking glamorous 365 days a year, she wrote on her Web site. I'll address everything from how your diet affects skincare and fun hairstyles for a night out to one simple thing you can do each day to freshen up your look.

True to form, Conrad asked fans to chip in with any beauty questions they would like to have answered.

Leave them in the comments below and I will check out all of your questions and work with my team to answer your beauty conundrums in the pages of my new book! How's that sound? she wrote.

Conrad has been expanding her style presence over the past year. Her upcoming book will complement Lauren Conrad Style, a fashion guide she published in October 2010. She is also part of, a Web site she helped launch earlier this year. Her personal Web site contains some pretty useful advice about style, health and even etiquette.

In a recent post, The Ladylike Laws: Why Manners Matter, she said she would soon begin writing about the topic of etiquette, beginning with a post about first dates.

I'm guilty of some of the worst offenses. I text during dinner, I forget to write thank you notes, I'm usually running late... Needless to say, I figured this series would be a fun and informative way for us to learn about the general dos and don'ts of modern life, she wrote.
