Los Angeles, California (CNN) -- Michael Jackson's son Prince wants to produce and direct movies, while daughter Paris hopes to be an actress when she grows up, the late pop star's children told Oprah Winfrey in an interview aired Monday.
Grandmother Katherine Jackson invited Winfrey's cameras into their Encino, California, home last month to talk about her son's controversial life and his sudden death last year.
"Sometimes in the day, I can hear his laughter in my mind," Katherine Jackson told Winfrey.
The last segment of the hour-long show featured the first time Prince, Paris and Blanket -- Michael's three children -- have been interviewed on camera.
"Tell her what you'd like to do when you grow up," Katherine Jackson said to Prince, 13.
"Produce movies and direct," he said.
Paris, 12, then spoke up.
"I'd like to be an actress when I'm older," she said. Paris assured Winfrey acting was a serious passion.
"I sometimes do improvs," she said. "I used to do it with my dad."
Blanket, 8, said little in the interview, beyond suggesting that his oldest brother was given more freedom when they lived with their father.
"He could get away with anything," Blanket said.
When family patriarch Joe Jackson joined his wife for a part of the interview, Winfrey asked about his infamously stern discipline practices with his nine children.
"I never beated Michael, like the media is trying to say," Joe Jackson said. Instead of beating, he would use a strap on them, he said.
His wife then spoke up. "You might as well admit it, that's the way black people raised their children," she said. "He used a strap. Yes, he did use a strap."
Winfrey asked Joe Jackson if he regretted using a strap on his children.
"No, I don't," he said. "It kept them out of jail."
Katherine Jackson spoke candidly about her belief that her son was addicted to plastic surgery.
"He was so unhappy," she said. "He thought he was so ugly."
It started with his first of several surgeries on his nose, she said.
"One day he just decided, he got up and said 'I'm going to get my nose done. It's too big,'" she said.
She said her son's nose eventually became "too small, like a toothpick."
She said his plastic surgeon didn't listen to her when she asked him to fake a procedure instead of actually operating.
