Spokespeople for Grande and Davidson did not immediately respond to TIME's request for comment. They had dated for two years, with the "God Is a Woman" singer referring to him as her "dearest friend".
Follwing the split, Ariana cancelled a performance at a charity event that was honouring her manager Scooter Braun's wife. "I believe in us and all, but you know, I just want to, like, make sure that she can't go anywhere", he said.
People took issue with the way Davidson casually joked about lying and manipulating Grande, and now, as it makes the rounds once more - people are making similar critiques.
News that the singer and the "SNL" comic pulled the plug on their engagement broke on Sunday - but sources told us there was buzz that they'd broken up the weekend before. Another insider close to the songstress told People magazine that it was just a matter of too much too soon.
Meanwhile, it has been a hard time for Grande after the sudden death of Miller.
The first was her slot as the Saturday Night Live performer for the show's season premiere just two weeks ago.
Last Friday, Grande released a music video for her new single "breathin", starring the couple's pet pig, Piggy Smallz.
Later, she tweeted to thank her fans for all of their love and support.
They still have love for each other and wouldn't rule out getting back together in the future, the source continued, but for now it's over for them romantically.
