Anyone who denies that there's tension between Camila and the rest of the girls needs to watch this You could see how uncomfortable she was whenever one of the photographers told her to move closer, and then she'd move farther away 5 seconds later.
Camila looks really uncomfortable like she doesn't want to be with them anymore, I can see Camila leaving like Zayn before the album gets released she would be a fool but if the rumours are true and Taylor wants her for her record label she is fine but I doubt Taylor would pay the penalization of her contract so maybe she will stay.
