Jaden and Willow Smith didn't just bump into MJ's kids on a movie set in L.A. yesterday -- TMZ has learned, it was all set up by Katherine Jackson ... to help nudge her grandchildren in a positive direction.
Sources close to Katherine tell TMZ, she believes the Smith children are prime examples of young success in Hollywood -- both extremely talented and down-to-earth -- and thinks Prince, Paris, and Blanket could learn a lot from them.
According to sources, Katherine wants to surround her grandchildren with role models like Jaden and Willow -- so she set up the meet-and-greet ... and we're told, the kids got along like a house on fire.
Katherine wants Michael's kids to enjoy their childhood -- and is actively encouraging them to become involved in all kinds of activities ... including acting.
