There were speculations that the couple, who have two kids together, were heading for a split after almost 20 years of marriage.
Will, 46, posted a denial on Facebook, adressing his wife as "queen." He also joked about those, who sent him their condolences after asuming the rumours were true.
"Under normal circumstances, I don't usually respond to foolishness. (Because it's contagious) But, so many people have extended me their "deepest condolences" that I figured - "What the hell... I can be foolish, too!"
Jada Pinkett's tweet followed a few minutes later. "My king has spoken," she wrote.
The couple married in 1997 and has been plagued by rumors in the past.
