Brad Renfro's Son Living In Japan

TMZ has confirmed that Brad Renfro had a young son who lives in Japan with his mom -- and the family is trying to keep details about the boy under wraps.

TMZ spoke with Renfro's dad, Mark, and his step-mom, Kim, who would not reveal their grandson's name or age in order to protect his privacy. They placed an obit in a local paper that simply listed his name as "Y Renfro."
