These ladies been together for almost 8 years now(2 years together as a girlgroup)..That’s explains the chemistry of the group..They always killed every performances and I love them so much..
just so you know, the haters even after this are still saying that it's not live, that's why they uploaded acapella versions on their channel to shut up all those haters once and for all.
Plus, if you watched the documentary and their training days, you know how much work Simon had them put into their singing lessons and not just their dancing, he trained them all around, which is what you see here!
