Girl group Fifth Harmony killed it at Pacific Amphitheatre on Saturday night, with members Ally Brook, Camila Cabello, Lauren Jauregui, Normani Krodei and Dinah-Jane Hansen delivering a solid opening, "Bo$$" for a clearly amped-up teen crowd.

Dressed in matching blue-sequined costumes and showing off an impressive display of choreography, the girls powered on with "Reflection" and "Going Nowhere," driving the crowd into a first-class frenzy. "Better Together" and "This Is How We Roll" followed a "We Will Rock You" mashup, before they took it down a notch for some slow ballads with "We Know", "Who Are You", and Jason Derulo's "Want to Want Me." The show closed with "Everlasting Love" and their hit, "Worth It", followed by an encore of "Body Rock".

Only time will tell how far up the charts the young ladies' music will climb, but since they struck the gates of fame in 2012 on "The X-Factor," the girls are showing no signs of slowing down yet.
