CRISTIANO RONALDO DOUBLE DATE ... With Michael Jordan
So ... who picks up the check?
Cristiano Ronaldo and Michael Jordan -- two of the wealthiest athletes in the history of the planet -- doubled up for a night out in the French Riviera ... because this is what extremely rich people do.
Ronaldo has been yachting it up with his longtime girlfriend, Georgina Rodriguez, and their kids -- but clearly, they got a babysitter and found some time for a night out with MJ and his wife.
Unclear where they went ... but with Ronaldo reportedly worth somewhere in the ballpark of a billion dollars ... and Jordan reportedly ALREADY in the tres commas club -- they can afford to eat anywhere they want!
Remember, Ronaldo has been sailing around on a $200,000-per-week yacht -- that comes with its own gym space and MOVIE THEATER!
