It was a meeting of the A-list celebuspawn as Michael Jackson's three kids (Paris, Prince and Blanket) hung out with Will and Jada Pinkett-Smith's children, Willow and Jaden Smith, on an L.A. film set the other day.


The Jackson kids arrived to the set with their grandmother, Katherine Jackson. So far, it's unclear if the kids were on the set to act ... or just to hang out with the Smiths.

As we previously reported, the Jackson kids have expressed a serious interest in Hollywood -- earlier this year, Prince told "Good Morning America" he was "looking at a couple of opportunities in show business ... mostly producing."
