had left the group, making this performance one that will go down in history.
Prior to the show the girls did an interview with iHeartRadio and some are saying it was a bit of tension between the girls. Take a look below and judge for yourself.
While all we have left are memories of the quintet, let's look back at their last performance on Dec. 18 and look forward to what it will be like to have just four of them on stage after this.
Check out their performance and let us know in the comments if you wish you were there to witness this in person.
