Money Mayweather’s crew just showed us how legends celebrate off the canvas! Instead of a flashy bash, Yaya and little KJ kept it chill at home, baking a cake together for his 5th birthday. The champ himself dropped some sweet throwbacks with his grandson, proving that even The Best Ever knows family time is undefeated. Anyone else love seeing the Mayweathers trade gloves for oven mitts? #Sports #Mayweather #FamilyFirst
