When Fifth Harmony hit up Las Vegas on Wednesday night, they were sadly down one member, with Camila Cabello mysteriously absent from the evening’s festivities. But don’t worry, Harmonizers -- before you run for the hills screaming bloody breakup, you should know the girls managed to recruit a stand-in who definitely knows a thing about putting in work (work, work, work, work, work, work).

Fifth Harmony Fourth Harmony reunited with their former X Factor judge Britney Spears at the veteran pop star’s residency show at Planet Hollywood. Together, the flawless fivesome took a group pic that can basically only be described with 100 fire emojis.

Normani Kordei tweeted the same photo as Ally Brooke, writing, “you went innnn tonight @britneyspears. thanks for having us babe. #itsbritneybitch.”

As if that pic full of “pretty girls” wasn’t enough to fuel the FOMO, Lauren Jauregui also shared a couple of snaps from inside the show, including one of Britney in action. “BRITNEY BITCH AHHH @britneyspears you did PHENOMENAL, my inner little Lauren was SCREAMING! Thank you so much for having us,” she wrote, shamelessly letting her fangirl flag fly.

Because it’s so amazing to see 5H and Britney’s paths cross again (a full four years after their stint on The X Factor), let’s celebrate #TBT by remembering that time the girls covered Brit’s hit “Oops!… I Did It Again” for MTV News. Such babies, but such talent.
