Fifth Harmony performed "Work From Home" for the first time as a foursome at the 2017 People's Choice Awards tonight (Jan. 18), their re-debut performance together since Camila Cabello left the group late last year.

And yes, they made sure to kick off a resounding declaration.

"We ain't worried about nothin', we ain't worried 'bout nada," the quartet fiercely declared before tearing into their construction zone-friendly anthem — no doubt a reassurance to their ever-loyal Harmonizers as they begin their new chapter down one member.

One by one, each member was given an intro by name on the big screen as the song went on. As a group, they teamed up for fierce choreography, live (if occasionally out-of-breath) solos and harmonies and one fiery dance break finish.

Welcome to Fifth Harmony reloaded. This is one girl group that's stronger than before.

Immediately after their performance, the girls picked up their award for Favorite Group and thanked their fans, families and the whole Fifth Harmony team.

If tonight was evidence of anything, it's that they ain't going nowhere: in fact, they recently confirmed a third 5H studio album on the way this year.
