Watch Miley Cyrus & Madonna Duet on "Unplugged"

 

Terrific ... or train wreck?

Miley Cyrus and Madonna's highly-anticipated duet aired Wednesday night on MTV's "Unplugged" -- and it was definitely interesting.
The song was the final performance of the night, and started with Cyrus singing "Don't Tell Me" from Madge's 2000 album "Music." 

FYI, Miley was only 8 when the album was released.

Then, the Queen of Pop came out of the audience and joined the young star on stage -- launching into a mashup with Miley's "We Can't Stop."
Both of their tongues made appearances, the two of them twerked on each other and we felt a little uncomfortable watching it all from our couches.  

Madonna was clearly trying to recreate some of the magic from her famous VMA performance with Britney Spears and Christina Aguilera ... but something about this was off.

What do you think? Are we being too hard on the performance or was it a bit messy? Sound off below!
