OK, so you know that Carrie Underwood did a duet with Steven Tyler  for rock band Aerosmith's latest album.
That song, "Can't Stop Lovin' You ," is now a radio single.
You've seen Steven and Carrie sing together before , including a mash-up of "Undo It" and "Walk This Way" at the ACM Awards in 2011. But how did Carrie come to record a song for an Aerosmith album?
"I sang it a little country and western," Steven told RollingStone.com . "When it was done, it was discussed that I might have sang it a little too country. And all along we thought, should we get someone in? It was last minute.
"[Carrie] was in town doing something. I called her up and she said, 'I'm leaving tomorrow.' And I said, 'Can you come over tonight?' I called [Aerosmith guitarist] Joe [Perry] up and the rest is history. She just did it. It really does work."
