She's just written a teen book called LA Candy which is a fictionalized account of life on a reality TV series. It's the first of three books.
Now I know some authors are annoyed that a famous reality star like Lauren can get a big book deal when they're still struggling to get noticed, but here's my take. If her book can get people who might not normally read to pick up a book, then they might discover they like reading. And then they'll pick up more books - by other authors! So everyone wins!! So this is a good thing, I promise. And honestly, if you write a good book - a really good book - you don't have to be famous to get noticed. I mean, who heard of Stephanie Meyer before Twilight? JK Rowling before Harry Potter?
Plus Lauren was super sweet and nice. Totally down to Earth and not pretentious at all. I really liked chatting with her. She definitely goes in the "celebs who don't suck" category. :)
