" They have invited the whole cast as well!
Sophia, Rob, Austin, Shantel.
So, expect to hear more conformations
As of right now, all I know is that Joy is going.
They have asked everyone on the cast about it.
I know Shantel wants to go, so she might be going as well.
Sophia and Austin, I have no idea at this moment in time.
