Last night this generation's biggest girl group took to the Jimmy Kimmel Live stage and got their "Work From Home" on... and it was dope! Not only are the girls killing it on the sales charts, but it's climbing high on radio and even streaming... so why not perform their hit live?

Check out the performance at the link, and yeah... the girls know how to work those sledgehammers!

What do you think Harmonizers? Will "Work From Home" be their biggest hit... yet!?
