The two were married only briefly, between the years 2000 and early 2002, but the recent news suggests a close friendship still exists.

Jolie wrote the foreword to Billy Bob's memoir last year, and he has spoken of his close friendship with both Angelina and her partner Brad Pitt.

Their marriage was known for its rather bizarre shows of affection, such as the wearing of lockets containing each other's blood.

Jolie revealed in May that she had undergone a double mastectomy to reduce her risk of developing breast cancer.
