In reply to Jomega.

I personally don't see how Camila was THAT big of a part of the group. I think they forced her on the GP. I think she was cute while it lasted, but I don't think she is a solo star. She may be a feature type star but hell if Ariana Grande can not find solo this with her big voice/range how is Camila going to?

I think that the four remaining girls could easily cover Camilas vocals and fill her void for future music. I mean how many girl groups have a mousey vocals girl doing they ad-libs? I mean usually its the big voice or the strongest fullest tone handling it. In that case any four can out do Camila for that role.

I do think with her departure this could be for a great genre switch to Urban R&B/Pop rather than Pop leaning R&B music that they've been doing.
