Jessica Simpson has a new autobiography that she is doing a ton of press for and it is full of some juicy deets. The book is cleverly titled Open Book.

Jessica dives deep into very personal issues dealing with her drinking and sobriety as well as stories about all her exes, including John Mayer!

But there are also a lot of lighter stories.

While on Jimmy Kimmel she tells the story of her audition for The Mickey Mouse Club. Ya, that MMC with Justin Timberlake and Ryan Gosling and Christina Aguilera and Britney Spears and so on and so forth. Well, Jessica didn't make the cut, but she kept in touch with a few of them.

Cut to her divorce from Nick Lachey, she and Justin Timberlake shared a kiss!! OOOOoooooh girl, tell me everything!

But get this, he kissed her because he and Ryan Gosling made a bet at 12 years old about who would kiss her first. I guess Justin won! Jessica said she actually had a crush on Ryan back in the day, though. (Go to the 4-minute mark for the Justin kiss story.)

The interview also touches on Jessica getting acting lessons from Chuck Norris, firing her dad as her manager, and her hilarious trips to the White House.

Open Book comes out on February 4th.
