Angelina Jolie and her ex-husband Billy Bob Thornton have reunited for his tell-all memoir titled ‘The Billy Bob Tapes: A Cave Full of Ghosts,’ due out this May. Jolie has written the foreword to 56-year-old ‘Sling Blade’ director’s book. It is described as, “spinning colorful tales of (Thornton’s) modest (to say the least) Southern upbringing, his bizarre phobias, his life, his loves (including his heartbreakingly brief marriage to fellow Oscar winner Angelina Jolie), and, of course, his movie career.” Jolie and Thornton were married from 2000 to 2003. The couple drew media attention when they admitted to wearing each others’ blood in vials around their necks. Now, Jolie has six children with her current partner Brad Pitt, who recently said in an interview that Jolie is still a “bad girl” but it’s not for “public consumption.”
