At a recent concert in Stockholm, Sweden, the boys of 1D performed a cover of the famous Backstreet Boys hit "I Want It That Way."
You can just imagine all the screaming from the female patrons of that show.
How did this come about? Well, One Direction chose to sing the song at the request of a fan during an open Q&A on Twitter during the show.
But here's the best part: The fellas at Backstreet Boys not only heard the One Direction cover but liked it as well!
"Heard @OneDirection did an impromptu performance of 'I Want It That Way' in Sweden last night. Well done bros!" read the message on the official BSB Twitter page.
This may have been the greatest musical collision of the past decade. Check out the video of the cover below (excuse the multitude of squealing girls). What do you think?
