The New Triple Threat?

The most common triple threat among celebrities is acting, singing, and dancing. So many celebrities can do it all (JLo, Britney, Justin Timberlake, just to name a few). But there is a slightly different triple threat that seems to be emerging among celebrities and it includes being a chick lit author. Here are some examples of the new trend:

Lauren Conrad - best known for her role on the reality show The Hills on MTV. She is a reality star, a fashion designer, and an author. She writes the L.A. Candy series about friends who move to L.A. and join the cast of a reality show. So original, right?
Nicole Richie - best known as Paris Hilton's former best friend and as daughter of Lionel Richie. She is a reality star, a fashion designer, and an author. Seeing a pattern? She wrote The Truth About Diamonds a few years ago and her new novel Priceless comes out next week. The Truth About Diamonds is about a girl who has a life very similar to Richie's. No surprise there.
Sharon Osbourne - best known as Ozzy's wife and for being on the reality show The Osbournes. She is a reality star, a television personality, and an author. She wrote Revenge, a book about two sisters who are both vying for fame.
Lo Bosworth - another person to come from The Hills. She is a reality star, a blogger, and an author. She wrote The Lo Down, which will be published in January. It is a book of dating advice. Technically, it probably isn't chick lit but it's close. She manages a blog of the same name.
Hilary Duff - best known as Disney's Lizzie McGuire, for various movie roles, and for singing. Hilary Duff is the exception to the new triple threat theory. She is an actress, singer, producer, fashion designer, and author. Oh, and she has perfumes too. Her first book, Elixir, comes out next month. It is about the daughter of a politician who is a photojournalist and has lived her whole life in the spotlight. Similarly, Duff has been in the spotlight since she was a child.

Aside from Bosworth's dating book, the pattern among these novels is that they are all about fame. Write what you know, right? I wonder if these novels really add anything to the genre. Would these celebrities ever have written novels if they weren't famous? Do they write only because they know they can get their books published? Are books just more things for them to sell under their already popular names? I question the intentions of celebrity authors. For them, books seem to be just another product. I think they release books because they can and not because they have always dreamed of being writers. I could be wrong but I'm skeptical of their intentions. What do you think?
