Woody Harrelson has said again that he “very much true”ly believes that he could be Matthew McConaughey’s biological brother. The 61-year-old actor stated that McConaughey’s mother, who had a brief marriage to the actor’s father, told him there was a possibility of a family tie between the two. Harrelson has never done a DNA test, but he claims he and McConaughey have many behavioral features and a deep connection. Harrelson has previously suggested that McConaughey get a DNA test done so that he may find out if he has a different father or a brother. McConaughey has previously discussed his speculation that his mother may have had a sexual relationship with Harrelson’s father, Charles, who is a professional hitman.
