This Is The Best Musical Collaboration Ever. But It Has To Be Said Miley Ruined It For Rihanna. Rihannas Got A Great Voice They Shouldnt Of Let Her Represent The R&B Divas If Its For A Good Cause Or Not Look At The Line Up Some Of The Worlds TOP Divas Then Uhmm Miley Cyrus? Yeaa..

Miley may not be the best singer or the most popular but at least she has the heart:D

This is one of my favorite charity songs that Mariah did. I am so happy that they all got together and did this. I was happy to have caught it on video! :-) thanks for the comments
