I have to admit beyonce and gagas videophone was a failure , but sometimes its not about who collab together its the quality of the song. e.g Live your life , right round , Just dance
I think the Rihanna-Ke$ha collab might be Rihanna's first all-female collab. She always works with males because she says she likes too. But finally she is showing some collaboration versatility
Why not? Tik Tok spent 9 weeks at #1 and Umbrella 10. They sure can. Don't think Gaga/Beyoncé failure is any indicative.
It wasn't a failure, but nice try.
Seeing the mention of Bey & Gaga makes me sad that you posters have forgot about the best collab between divas of them all... Brandy & Monica's "The Boy Is Mine". Other mentions Whitney & Mariah's "When You Believe" and X-Tina, P!nk, Mya & Kim's "Lady Marmalade".

She worked with Nicole Scherzinger, even though Winning Women never got a proper release. (Because they always put the wrong single on iTunes, WW would've taken off.)
Robert Plant, the legend?!??! 
In your dreams.
. 10 weeks is acceptable in US.
