During the Twitter Q&A, Liam, Louis, Harry, Niall and Zayn were asked "Can you sing Backstreet Boys 'I Want It That Way'? Love!"
Never ones to back down from a challenge, the 1D guys burst into their best BSB cover of the throwback boy band tune.
Okay, so obviously they're not well-rehearsed with the song, but they made the most of it.
Some Backstreet Boys fans have complained and dissed the guys for their performance, but given the on-the-spot request, we think they rose to the challenge pretty well.
No matter if you loved One Direction's "I Want It That Way" cover or hated it, the guys have one vote of confidence--the Backstreet Boys tweeted a link to the video with a compliment, writing:
"Heard @OneDirection did an impromtu performance of "I Want It That Way" in Sweden last night. Well done bros!"
It's the boy band brotherhood!
