Christina Aguilera "connected" with Demi Lovato because they both felt "misunderstood".
Christina heaped praise on Demi as she described her like a "soul sister" as she feels that both of them have experienced the same thing but in two completely different generations.
Christina said Demi's the "epitome of fighter and survivor"
And she thinks Demi was so brave to share her story after she was hospitalised due to a near-fatal drug overdose in July 2018.
