Grande went to her Instagram Story Tuesday (October 16) with some upbeat words.
A rep for Grande did not immediately respond to a request for comment, while Davidson's rep had "no comment" regarding the apparent split.
However Ariana Grande, who had remained silent, has now tweeted for the first time since the announcement.
"Calling off the engagement was Ariana's choice, but she is still heartbroken and never wanted to hurt Pete", our source explained. However, it doesn't appear that there was any big real change overnight that caused the split, but instead it was a drawn out process that began with Mac Miller's death from overdose last month, according to TMZ.

The Duke and Duchess of Sussex's baby could end up sharing their birthday with great-grandmother the Queen or cousin Prince Louis. In remarks which went from honest to humorous, the duke spoke of his pleasure at being able to show off Australia to the duchess.
A source told People that the death of Grande's ex, Mac Miller, in September had a huge impact on the singer and may have affected her relationship with Davidson.
The pop star, 25, and Saturday Night Live actor, 24, started dating in May - the same month it was confirmed she'd ended things with the rapper - and they were engaged by mid-June. Grande and Davidson (or "Grandson", as they're known) managed to truly ignite the Internet this summer, as observers gawked at their new and very public love.
