The 4 oldest sisters; Christina, Katherine, Lisa, and Amy (all) moved to an apartment all together when moving to Nashville. That also means (that) Dani & Lauren don't share a room anymore and it's just them and their 3 younger brothers in the Cimorelli household now, not including their parents (Alex is 18, almost 19, and I don't remember if they said that he lived with them or not, so I'm not going to mention anything until I know). Ps, each room is shared by two sisters. Christina & Katherine share a room, while Lisa & Amy share a room together.
