Will & Jada Pinkett Smith -- Kids' Fame at Root of Summer Marriage Troubles

Will Smith and wife Jada Pinkett Smith have bounced back from the separation rumors that plagued them earlier this year ... and TMZ has learned it was differing opinions on how to manage their superstar kids that caused the original strife.

Sources close to the couple tell TMZ they are doing "wonderful" now -- but earlier this year, sources tell TMZ there was tension between the two over how best to manage the careers of Jaden and Willow.

We're told each had their own ideas for how things should be handled -- with Will pushing more for full-blown stardom and Jada leaning towards easing them in to things.

But our sources say that bad patch -- which included rumors Jada had an affair with Marc Anthony -- is now past them and things are back to normal.
