Although it wasn't as crazy as a Thai sex show, it was still pretty darn good!
RiRi chose to performs Diamonds after accepting her Icon Award, which we thought was an interesting choice!
She probably should have gone with What Now considering it's her new single! But hey, she's the icon here!
Afterwards, RiRi brought her adorbz mom to the stage and gave a heartfelt speech while accepting her much deserved award!
Take a bow, gurl!
Ch-ch-check out her iconic performance (above)!!!
