Skip ahead to the first chorus in both of the below videos (under the tweet) to hear what many fans and concert-goers have notices and are pointing out on Twitter.
It would appear that Fifth Harmony is still using departed member Camila Cabello's vocals while on tour. Camila left over 3 months ago. Unless they had an agreement with Cabello, you would think that the group would have completely re-recorded their songs by now without her voice. Or at least not used her recorded voice at concerts.
Let us know what you think in the comments!
