Well, this is a little awkward.
The pair not only recorded the song separately, but they filmed the Airplanes video separately too.
B.o.B. says, "You know I've always wanted to work with Hayley. I've still never met her yet, which is ironic and funny at the same time because this is, like, one of the most popular songs, but we've still never met."
Meanwhile, Hayley joked that they've only communicated with each other on Twitter. "We'll never meet. We're going to perform the song live via Skype."
We would totally love to see that!
