After seven years of dating, George Lucas has finally put a ring on it. The 68 year old Lucas is engaged to his 43 year old girlfriend Mellody Hobson. So, if my math is correct he was 61 when they started dating and she was 36. I guess he is trying to get married before he turns 70. I wonder what made him finally ask. Maybe the sale of his company? Mellody is the president of an investment company in Chicago.
