Ally Brooke, Dinah Jane, Lauren Jauregui and Normani Kordei arrived at the 2017 People's Choice Awards last night ready to slay! Dressed in sexy leather outfits, the girl group took the stage to perform "Work From Home," even tweaking a few of the lyrics: "We ain't worried 'bout nothin', we ain't worried 'bout nada." Not only did the ladies deliver a stellar performance, they also took home the PCA for Favorite Group, which was presented to them by DJ Kahled.

"Thank you guys so much! Thank you, this means the absolute world to us," Normani said during their acceptance speech. "We want to thank our Harmonizers, for everything that they do for us. We would be nothing without you, please believe that. We love you so, so much." Lauren continued: "We want to thank our families, our team, our team, our team, our team! They are some amazing people. Thank you anyone who's supported us, we love you. Thank you! So much to come, stay tuned!"

This was the group's first performance and award win without Camila Cabello, who left Fifth Harmony in December 2016. "After 4 and a half years of being together, we have been informed via her representatives that Camila has decided to leave Fifth Harmony," a statement via the band's Instagram said. "We wish her well."
