With [article id="1614354"]"L.A. Candy"[/article] becoming a bestseller last year, it's time for Lauren Conrad to prove that she has what it takes to move more books with the second novel in her trilogy, "Sweet Little Lies." While the story of reality-TV star Jane Roberts is a work of fiction, Conrad said the lessons she learns are very, very real.

"I think that if fans take anything away from the book, [they should realize] there's a back side to every story," she told MTV News while on her book tour. "And when you're reading tabloids and seeing these people's lives exposed, it does affect them and it is hard to go through as a young girl."

Conrad, who left "The Hills" last year, revealed that when it comes to dealing with the pressures of fame she and Jane both realize "you live and learn," adding, "I think we deal with it the same."

So what has Jane learned in the new book? Well, that it's probably best not to take nude photos, and also to be a lot less naïve about the pitfalls of fame or the motives of the people around her. "The second book basically picks up where the first book left off so it kind of just continues to tell the story. It gets a little bit deeper into Hollywood and the behind-the-scenes look of a reality show," she explained. "There's a new guy ... I think that in the first book she was a little bit naïve -- the second book is where she gets burned and after that is where she is gonna grow."

However, Conrad admits that when she got on her start on "The Hills," she understood the dark side of Hollywood a lot better than Jane does. "I made a Jane a little more naïve than I was -- other than that she was pretty similar. It was easier to tell the story in my own voice -- when you're writing it comes very naturally," she said. "The emotional moments where she's going through things and being frustrated and kind of overwhelmed -- those are me."
