Matthew McConaughey and Woody Harrelson: Brothers?

During an appearance on Kelly Ripa's podcast, Matthew McConaughey hinted that he and his "True Detective" co-star Woody Harrelson might be brothers after his mother revealed that she knew Harrelson's father. McConaughey said they are considering taking a DNA test to confirm any blood relation, but he is hesitant. The two actors have a close friendship, with their kids often confusing them in photographs. They are also working on a new project together titled "Brother from Another Mother."
