Camila Cabello Responds To Fifth Harmony's Statement

Camila Cabello is calling BS on Fifth Harmony claiming to be blindsided by her leaving the group ... and insists everyone's known she'd be hittin' the road for a while now.

Camila posted a lengthy response to Fifth Harmony's own brief statement earlier Monday morning, saying the claim of her reps breaking the news seemingly out of nowhere is "simply not true."

She adds ... she and the other girls have talked openly about going in on their own solo projects for quite a while ... as indicated by the other members' own statements.

Camila goes on to thank her Fifth Harmony fans, and even invites them to follow her example.
