Will Smith: 'Son could be bigger than me'

Will Smith has joked that his son Jaden could become a bigger star than him.

The 12-year-old appears alongside Jackie Chan in The Karate Kid, which was produced by Smith and wife Jada Pinkett Smith.

He told PA: "The Karate Kid three-day box office was $56 million in the United States which was bigger than any of my movies other than Hancock and I Am Legend, so for me I'm wondering if he even still needs to live at our house."

He added: "People started calling me the Karate Kid's dad, I was like alright, Men In Black 3 is out immediately!"

The 41-year-old actor admitted that he cries when watching his son act.

"I don't choke back the emotion, I boo hoo every time I see him! It was excruciating for Jaden to be squashed particularly between Jackie and myself," he said. "He's so disciplined and so hard-working, it's hard to not push him for more, you know, it's like there's no telling what this kid could do.

"It was such a wonderful experience and any part of that movie still chokes me up and as far as him still having pieces of me, he's truly his own thing. He has the best of Jada and I - it's just amazing that you can go to Mexico, drink some tequila and then he shows up nine months later!"
