In the aftermath of the sudden death of rapper Mac Miller, Ariana Grande has been forced to block comments on her social media platforms.

Ariana and Miller were together for two years before splitting in May. A short time later, she and actor and comedian Pete Davidson announced their engagement. However, and despite Miller's historic battles with addiction, Ms Grande and her new partner have been at the receiving end of huge amounts of online abuse since the death was announced by TMZ on Friday. Comments on Ariana's Instagram even claimed she was responsible for the death. https://twitter.com/NalediMashishi/status/1038321162172948480 "Within less than 10 minutes of the initial report surfacing," reports DailyMail.com, "Grande had closed the comment section on her Instagram account, but not after dozens of users posted nasty messages such as 'This is your fault' and 'You did this to him'." Sources cited by ET also say that Ms Grande is nothing short of "heartbroken" and "devastated" by her former boyfriend's death.

"Although the two ended their relationship, Ariana always shared a deep connection with Mac and wanted nothing but the best for him. Ariana is very upset," one source told the website.

"Despite their split, Ariana had always been supportive of his sobriety," a second source added.

Pete Davidson has 2.4m followers on Instagram. He currently has no posts on the platform. However - and although one story shared online stated that he deleted his photos when Miller died - he had already cleared his grid before news of the tragedy broke. In July, Davidson explained why he removed his photos. "No nothing happened. No there’s nothing cryptic about anything. I just don’t wanna be on Instagram anymore," he said at the time. "Or on any social media platform. The internet is an evil place and it doesn’t make me feel good." Mac Miller was found at his home in the San Fernando Valley outside Los Angeles at around midday on Friday. He was pronounced dead at the scene by paramedics, according to a report by TMZ.

It is believed he died from a drug overdose.

"Miller has had trouble recently with substance abuse... in the wake of his breakup with Ariana Grande," reports TMZ. https://twitter.com/sweetenerlilly/status/1038323222503219200
