It was alleged earlier this week that Will and Jada had separated after 13 years of marriage, but the couple soon released a joint statement insisting that they are "still together".
Will's Fresh Prince co-star Ribeiro was questioned by a photographer about his friend's marriage on Wednesday as he exited an LA restaurant.
Ribeiro told TMZ: "[Will and Jada are] not getting a divorce. They're all good."
Jada and Will wed in 1997 and are the parents to 13-year-old son Jaden and 10-year-old 'Whip My Hair' singer Willow.
Trey, Will's son from a prior marriage, has also suggested that his father and Jada have no plans to end their marriage.
