And now, the 2017 Billboard Music Awards performance you didn't see during the orginal broadcast.

Camila Cabello made her awards show solo debut on Sunday night (May 21) with a fiery, hair-flinging performance of her debut solo single "Crying in the Club," featuring a brief opening of The Hurting. The Healing. The Loving. album track, "I Have Questions."

But what you probably didn't know is that Camila performed that song in full, as part of an encore performance presented by Xfinity.

The emotional encore, complete with two interpretive dancers and hundreds of red petals, includes some pretty unique camerawork to give the performance a surreal touch, moving backwards in moments. As Camila reveals in a behind-the-scenes clip from Xfinity, Camila needed to learn some of the performance in reverse in order to make that video magic happen.

"We knew that we wanted it to be kind of undone and intimate. I wanted it to feel like me kind of feeling this monologue," she explained.

"The cool part is that parts of it were filmed in reverse...I had to learn the vocals in reverse. I downloaded this reverse speech app on my phone and I went word by word. I learned every little thing in reverse."
