Fifth Harmony is disbanding for the unforeseen future.

E! News reported that the girl group — made up of Dinah Jane, Normani Kordei, Ally Brooke and Lauren Jauregui — announced on Twitter on Monday they are going on "solo endeavors" and are going on a hiatus.

Fifth Harmony began as a five-person group, forming on the US version of “The X Factor” in 2012. In 2016, original member Camila Cabello controversially left the group and launched her own successful solo career.

"Reflecting on the past six years since we started on X-Factor, we've realized just how far we've come and we appreciate everything so much, more now than ever," the statement said. "We've really had one hell of a memorable journey together and can't begin to express our gratitude to y'all for coming along with us on this wild ride!

“After six years going hard, non-stop, we also realized that in order to stay authentic to ourselves and to you, we do need to take some time for now to go on a hiatus from Fifth Harmony in order to pursue solo endeavors.”

The group ended its statement with a thank you to their fans, called Harmonizers:

“To our Harmonizers, thank you for everything we have been able to build as Fifth Harmony. With your love and encouragement we will continue to build on ourselves, support one another in everything we do, and keep making you proud, each other proud and ourselves proud.”

Fifth Harmony still has tour dates that it says will still happen through the end of the year.
