Fifth Harmony, Camila Cabello decided to separate ways - for whatever reason, it's not revealed yet. However, the pop girl group had already announced via their Instagram that the young singer, Camila Cabello is leaving the billboard-topping group.

According to Billboard, Fifth Harmony has revealed Camilia Cabello's departure from from the group. In their statement, the rest of the Fifth Harmony girls revealed: "After being together for four and a half years, Camila's representatives have informed us that she has decided to leave Fifth Harmony, we wish her well."

Fifth Harmony to Fourth Harmony? It can be recalled that these five girls individually auditioned for X-Factor US in 2011. They failed to make it in the final list only but were fortunate enough to be formed by no less than Simon Cowell prior to the next stage of competition. Their combination proved to be a hit and their chemistry is undeniable. Eventually, they surpassed other acts, established their identity as a group and finished in the Top 3 of the competition.

Clearly emotional, the girl group thanked their supporters: "You, Harmonizers, were there from the start. You've supported us and we felt your love as we continue on. That being said, we are thrilled to announce that the four of us - Ally Brooke, Normani Kordei, Dinah Jane and Lauren Jauregui will stay together as four strong-willed, committed women and we'll bring you Fifth Harmony that's better than ever."

They also hinted that whether they go solo or not, Fifth Harmony will stay intact. They also teased their followers about the new things to come in 2017. However, fans were visibly surprised about Camila Cabello's sudden exit from the group.

In one of their concerts last September, Cabello went off the stage in the middle of their performance after experiencing another episode of anxiety attack. She then said sorry and performed together with her girls the next day.

As for the reason for her departure from the group, 2016 had been rough for Cabello and the rest of Fifth Harmony. In one of her interviews with Billboard in May 2016, Cabello revealed her struggles and anxiety due to fame: "I was having non-stop, terrible anxiety attacks. I was fearful of everything and what my brain tells me. I realized my health is important. Now, I write my thoughts in my diary everyday, work out and meditate."
