Angelina Jolie Wrote The Foreward To Billy Bob Thornton's Memoir

Looks like she's not too concerned about him spilling any dirty details in his new autobiography!

Angelina Jolie has written the foreword to ex-husband Billy Bob Thornton's new memoir, The Billy Bob Tapes: A Cave Full of Ghosts, according to a rep for HarperCollins.

Thornton co-wrote to book with country music singer/author Kinky Friedman, and it will cover everything from his childhood to his phobias to his relationship with Jolie.

Thornton and Jolie were married from 2000 to 2003, and it wasn't just their 20 year age difference that turned heads. The odd couple wore vials of one another's blood around their necks and they once admitted to having sex in their limo on the way to a red carpet event. Looks like there will be plenty of material for him to discuss!
