Demi Lovato has been struggling with "survivor's guilt" ever since rap icon DMX was hospitalised following a suspected drug overdose.
The Party Up (Up in Here) hitmaker, real name Earl Simmons, has been under doctors' care in White Plains, New York since Friday night, when he suffered a heart attack.
He was placed on life support, with his manager, Nakia Walker, revealing he is in a "vegetative state with lung and brain failure", and medics are now running various tests on the rapper to determine his level of brain activity, if any at all.
And the tragic turn of events for DMX, who has a long history of substance abuse troubles, has reminded Demi just how close she came to losing her life in 2018 after her own heroin overdose.
