Ariana Grande defends her decision to end 'toxic' relationship with Mac Miller.

Ariana Grande has defended her decision to end her toxic relationship with Mac Miller, after a fan attacked her on Twitter for “dumping him for another dude”.

The Twitter user referred to the breakup as “the most heartbreaking thing happening in Hollywood” and questioned why Ariana would break things off with her rapper boyfriend after he “poured his heart out on a ten song album to her”.

In response, Ariana set the record straight on why she ended the ‘toxic’ relationship shortly after Mac Miller totalled his vehicle in a car crash. At the time of the crash, Mac’s blood alcohol content registered double the legal limit.

The singer wrote: “How absurd that you minimize female self-respect and self-worth by saying someone should stay in a toxic relationship because he wrote an album about them, which btw isn’t the case (just Cinderella is ab me).”

“I am not a babysitter or a mother and no woman should feel that they need to be. I have cared for him and tried to support his sobriety and prayed for his balance for years (and always will of course) but shaming / blaming women for a man’s inability to keep his s— together is a very major problem.”

“Let’s please stop doing that. Of course I didn’t share about how hard or scary it was while it was happening but it was. I will continue to pray from the bottom of my heart that he figures it all out and that any other woman in this position does as well,” Ariana concluded.

The fan later publicly apologised to Ariana on Twitter, writing: “I’m very sorry I hurt you and I’m sorry you feel my tweet stigmatises women for ending a toxic relationship”.

According to People magazine, 24-year-old Ariana is reportedly now dating Saturday Night Live comedian Paul Davidson.

A source reportedly told People, “Ariana was holding Mac together for a long time and it wasn’t a good relationship for her. She is in a very good place and very happy now.”
