Angelina Jolie and Billy Bob Thornton have reunited – in the pages of a book.
Jolie, who divorced Thornton in 2003, has written the foreword for her ex-husband’s upcoming memoir, The Billy Bob Tapes: A Cave Full of Ghosts, due out May 15.
Jolie isn’t the only famous person who contributed. An image of the cover of Thornton’s book posted on Amazon reads, “Introduction by Angelina Jolie, with commentary by Robert Duvall, Dwight Yoakam and Tom Epperson.”
