Cristiano Ronaldo Rocks Surprising New Blonde Hair

Cristiano Ronaldo is rocking a new look ... and he totally looks like he could join a boy band if the whole soccer thing didn't pan out.

Check out the snaps ... the international superstar just got hitched to model Georgina Rodríguez ... and clearly decided it was time for a new blonde 'do with his "I do."

Cristiano's natural hair color is jet black -- and usually styled with a classic fade that's longer on top ... but now it's blonde and buzzed.

Reaction to the new look is mixed ... but mostly positive on social media -- which makes sense since the dude is idolized around the globe by soccer fans.
