Jada Pinkett Smith is speaking out about her reportedly troubled marriage ... calling these claims "ridiculous."

Will's 40-year-old wifey tells French magazine Gala:

    "These rumors are completely untrue. I travel a lot because of my work, just like Will does. ... but our lifestyle hasn't changed. Before we had the kids, we were already far away from each other quite often because of separate projects."


As for how she thinks the rumors started, Jada says:

    "I have no idea! Every year, one celebrity couple is under the microscope. This year, unluckily, it's us! I almost want to say that we should have been expecting it."


Are they living together? She adds, "That's ridiculous. We've always lived together."
