Today on Oprah, Katherine Jackson opened up about her son's "addiction" to plastic surgery, saying that she urged him to stop and even asked his doctor to stop working on MJ. She likened his nose to "a toothpick."

Oprah also got a chance to speak to the various grandchildren that Katherine is raising, including Prince, Paris and Blanket. The kids shared their favorite memories of their father, which almost always included eating Snickers bars.
