Ciara Bursts Out Laughing When Asked About Co-Parenting with Future

ONE LAUGH = A THOUSAND WORDS TSR

Ciara and Future share a child, legally and biologically speaking, but, if you ask her about his style of co-parenting ... be ready for side-splitting, nonstop laughter!!!

That's exactly what happened when Thembi of The Shade Room closed their interview by asking Ciara about how she and Future co-parent their 9-year-old son Future Zahir.

The question was an instant humor injection for Ciara -- but, for a moment, it seemed as if she was actually going to answer the question ... until she just erupted in more laughter, and then the giggles got the best of her and Thembi.

TAKIN' SHOTS AT RUSSELL

Of course, Future's been taking shots at Ciara's husband Russell Wilson…
