Mel Gibson's 93-year-old dad has filed for divorce. According to a petition filed at the Los Angeles Superior Court today, Hutton Gibson cited irreconcilable differences from his wife of ten years Teddy Joye Gibson, who is reportedly in her 70's. The pair tied the knot in 2002. Hutton did not have any children with Teddy - who was Mel Gibson's stepmother. Mel's mother Anne, who had 11 children with Hutton, passed away in 1990.
