On May 22, 2017 - a suicide bomber detonated a bomb after Ariana's gig in the Manchester Arena, killing 22 people and injuring hundreds.
However, Ariana's fans caught the story that she had posted and reposted it for others to see.
Following the tragic event, Grande returned home to the United States and sought refuge at her mother's home in Florida, but amazingly, the singer returned to Manchester only a few days later.
The songstress bid the year a big "thank you, next" on New Year's Eve as she wished her fans well in the year ahead. "She milkin this shit bruh", said a twitter commenter.
She also recently explained that she had held off announcing dates for her Sweetener tour in Manchester, but did tease she had something "special" planned.
Opening up about her right to grieve her ex, Grande added that "everything i feel is valid and safe". It will likely take months and years before she can accept such a devastating loss. "It's impossible to know where to start or to know what to say about this part". "All I've ever tried to do was help people".
A couple of weeks after the atrocity, Grande set up the One Love Manchester benefit concert on 4 June which raised money for victims and their relatives. It is expression. It is happiness.
"When something so opposite and so poisonous takes place in your world that is supposed to be everything but that... it is shocking and heartbreaking in a way that seems impossible to fully recover from".
