IT'S ALREADY HAPPENING!!!!
Dustin Johnson and Paulina Gretzky's 1-year-old son is getting lessons on how to be hockey's next biggest thing ... from grandpa Wayne!!!
Paulina and D.J. posted the adorable vid of Rivers Johnson -- their youngest child -- with The Great One ... and we gotta say, it's hard not to see the resemblance.
