Ariana Grande mourns Mac Miller's death with photograph

Ariana Grande has mourned the sudden demise of her ex-boyfriend Mac Miller by sharing a picture of the rapper on her Instagram.

The 26-year-old rapper was pronounced dead on Friday from apparent an overdose.

Grande, 25, shared a black-and-white photograph of Miller looking at the camera while sitting on the grass.

The pop star shared the image without a caption.

Grande disabled comments on the social media platform after some fans began to blame her for Miller's death.

The duo dated for two years before their break up in May. After their split, Grande started dating comedian Pete Davidson with whom she got engaged in June.

Miller, whose real name was Malcolm McCormick, was pronounced dead at 11:51 am at his Studio City, California, home on Friday, the Los Angeles County Department of Medical Examiner-Coroner confirmed. A cause of death is yet to be determined.
