Oprah Winfrey, whose relationship with her dad Vernon has been contentious at best, called him yesterday to wish him a Happy Father's Day, the daytime legend revealed in a surprising email to fans on Sunday.

"I already called my Dad, since I knew I'd be traveling out of the country today," Oprah wrote adding, "Happy Father's Day to all you great dads. And to those of you who are trying to be better; recognizing that you're not a man because you can make a baby ... You're a man when you can raise one. I salute you for the work and sacrifice and the dream you carry day in, day out for your family."
