Woody Harrelson confirms he wants to get a DNA test with Matthew McConaughey to see if they're actually brothers

Woody Harrelson has confirmed that he wants to get a DNA test along with Matthew McConaughey to see if the two are half-brothers. The "True Detective" costars have been friends for quite some time, but a few years ago, they learned they may have the same father.

McConaughey revealed last week on Kelly Ripa's radio show, "Let's Talk Off Camera," that his mother had mentioned years ago while they were all vacationing in Greece that she "knew" Harrelson's father, and noted that "it was a loaded K-N-E-W."

During an appearance on "The Late Show with Stephen Colbert" on Tuesday, Harrelson said "there is some veracity," to McConaughey's belief they could be brothers.
