@King :

i co-sign with almost all of your last comment " especially the part about gaga and beyonce" that's also what i think , like the same opinion of mine , except for ;

1. rihanna is not known for her collabos , maybe her looks , maybe her fashion style , but not collabos. she has hits with only her name on it. :)

2. beyonce outshined gaga only in the video , maybe cuz everyone was amazed how beyonce got adopted the elements of gaga's world that quick " that paparazzi's sunglasses for example " , but not in the song.

3. rihanna is all about Fun, she's always fun and that's itself one of the reasons i love her :)

the two R will be cool together " Rita and Rihanna" :) , i'm all for uniting and not for comparing artists :)
