While were talking to the popular female duo on the Cambio blue carpet at the Billboard Music Awards, we asked them how they felt knowing that Taylor Swift listens to their song "I Don't Care" before she performs.
Obviously, they were thrilled! They also said they would absolutely love it if she jumped up on stage and performed with them tonight.
Seriously, how cool would that impromptu collaboration be?
The girls also told us how it feels to be attending their first Billboard Music Awards and what they are planning for their performance tonight (that is, if Taylor doesn't join them on stage!)
Check out the video above to hear what they had to say.
