Ariana Grande straight up said she loves Demi. Ellen said he heart is breaking that Demi is going through this (I'm assuming she meant the overdose and moreso the battle with addiction overall). Ruby Rose, who Demi has been rumored to be spending some extra time with, said her whole heart and soul are with Demi.
On one hand, it's a bummer that words like these are only exchanged during tragedies. On the other hand, I'm sure when Demi needs to hear things like this the most -- it's great that she has a freakin cornucopia of love being sent her way from fans and peers.
