Just a couple weeks ago people were freaking out about her Instagram activity, and while I understood the concerns, there wasn’t a whole lot to go on. So while things seem a bit vague about exactly what she will be doing with the group, having the announcement being made at an official event definitely seems to bode well that it’s actually happening.
