Angelina Jolie wrote the foreword for her ex-husband, Billy Bob Thornton's new memoir, "The Billy Bob Tapes: A Cave Full of Ghosts," according to a rep for HarperCollins .
The news comes amidst rumors that Thornton's new film may be based on his wild romance with Jolie, his fifth wife. Jolie is now in a highly-publicized relationship with Brad Pitt, with whom she has six children.
Thornton's book, out on May 15th, promises to spin "colorful tales of [Thornton's] modest Southern upbringing, his weird phobias, his life, his loves (including his heartbreakingly brief marriage to fellow Oscar winner Angelina Jolie), and, of course, his movie career."
Thornton and Jolie married in 2000, despite their 20 year age difference, and quickly distinguished themselves as one of the most eccentric couples in Hollywood, known for wearing vials of each other's blood around their necks.
While they divorced in 2003, there appears to be no bad blood between the popular exes.
In 2010, Thornton said of Jolie, "We talk every now and then. She seems to be doing very well directing her own movie, which I am so proud of her for. She's real smart, and very creative, and I think it's a great job for her."
