It's a sad day in the Harmonizer world. 

Fifth Harmony has announced that after four years in the band, Camila Cabella is leaving the group.

Since her collaboration with Shawn Medes on the single “I Know What You Did Last Summer," rumors stirred that Camila would leave Fifth Harmony.

The single reached the top 20 on the US Billboard Hot 100.

And though the singer did stick it through another year, Fifth Harmony went on social media to announce the official split.

This news comes hours after the group rocked the stage at the Jingle Ball show in Miami.

The remaining members – Ally Brooke, Dinah Jane Hansen, Lauren Jauregui, and Normani Kordei – will continue the group. So don't fear, Harmonizers!

The girls wrote to fans saying, "You Harmonizers have been there with us since the beginning, you’ve supported us, you’ve rejoiced and cried with us, you’ve grown with us, and with your love and support we will continue on."

They added, "We are excited to announce that we will be moving forward with the four of us … We are four strong, committed women who will continue with Fifth Harmony as well as our solo endeavors."

But how exactly do the girls feel about Cabello leaving the band? Well, soon after the news broke, the remaining girls were quick to remove Camilo from their Twitter bio.

The shade is real!

And while it’s unclear whether the girl group will rebrand themselves as “Fourth Harmony” – like many fans are already doing – Harmonizers have taken to social media to voice their opinions on the break up.

Of course, many Harmonizers were heartbroken...

But some were far less surprised...

... like this Twitter user who ~predicted~ the split.

BUT HOW!?

And Camila might just be the new Zayn...

...all while being compared to the Blac Chyna of the group.

But thanks to the split, we might being seeing a Carpool Karaoke soon.

Earlier this month, the group announced a third album underway. I guess only time will tell whether the album will be completed.

While we all have many questions, we wish the girls – as well as Camila – the best of luck in all their future endeavors.
