Rihanna Rocks Out with Bon Jovi

Duets don't get much more unexpected, or awesome, than this.

At a concert in Madrid last night, Bon Jovi broke out its classic single "Livin on a Prayer." The crowd was going ballistic enough over it when a special guest appeared on stage alongside the lead singer: Rihanna!

Tweeted the beautiful artist after the performance:

“Wait!…did I just rock out with Bon Jovi tonight??? WTFFFF!!!!!!!”

Yes, yes you did. See for yourself, readers, in the video below.
