Jamie Foxx made a super timely joke about Black History Month and white chicks ... which we're sure Katie Holmes is gonna love.
Jamie threw a super baller NBA All-Star basketball tournament "Chacha The Wave" Saturday at his house in Thousand Oaks, CA -- and stopped to talk to a photog about BHM and "Black Panther." That's when he declared, "No white girls 'til March 1st."
Great line from the comedian, especially considering what had happened the day before ... when he walked out of a live ESPN interview because they brought up Katie.
Maybe he was just respecting the white girls' ban.
JK. We all know he and Katie are waist deep into their relationship -- have been for years -- so, we're guessing, he's only making the joke because they're that tight.
Bonus fact: Jamie's whip in this clip is a Rezvani Tank ... a limited edition ride that costs about $200k!
