Angelina Jolie has penned the foreword to ex-husband Billy Bob Thornton'supcoming memoir.

The couple was married for three years at the start of the new century and the actor/director has often insisted he is still friends with his ex- and now, as if to prove the point, her thoughts will feature in his book The Billy Bob Tapes A Cave Full of Ghosts.

Thornton co-wrote the tome with country music singer and author Kinky Friedman.

Publishers at Harper Collins insist the tell-all will details the actor's upbringing, his infamous phobias, his movie career and his five marriages.
