Kristin Cavallari, Audrina Patridge The Hills Beverly Hills Kristin Cavallari and Audrina Patridge were filming a scene for the final season of their show, The Hills yesterday afternoon and we bet Kristin just cannot WAIT for it to be over?

Why? Because she's planning on writing a tell-all book as soon as she cashes her final paycheck!

"After The Hills, I plan to work on many business opportunities, and I have always wanted to write a tell-all book," the starlet tells In Touch of her plans to follow in Lauren Conrad's footsteps in more ways than one.
