But the girls say this far from a farewell and more of a celebration with the band planning to return to the studio later on in the year to start recording their fifth studio album.
Instead, they are releasing a Greatest Hits at the height of their fame so fans can look forward to finally getting all the hits on one album.
“We can’t wait to get out on the road and showcase our journey so far,” said band member Frankie Sandford.
“This is not the end, just a milestone along the way.”
