Do Ke$ha And Rihanna Have A Collaboration In The Works?!

According to some thinly-veiled hints on Ke$ha 's Instagram, then we'd say it's a definite possibility!

That's right, the singer is expected to drop Die Young, the new single from her upcoming sophomore album any day now, but took to the social networking site yesterday to share a photo of a Waffle House waitress holding up a napkin with Rihanna 's iconic 'R' insignia drawn upon it, along with the caption:

what's it all mean???

Ch-ch-check out a comparison (above)!

GAH! We don't know!

Well, scratch that: we HOPE we know what it means!

And given that RiRi is also hard at work on her next album, it's certainly a possibility that these two would want to hit the studio together!

Oh man! Think about all of the MAGIC these two could make with their powers combined!

Talk about EPIC!

Fingers crossed that we'll have an answer soon!

What do U think?? Do U want to see a Ke$ha/Rihanna duet?!
