Per the reports, the pair apparently "still has love" for each other, but things are over - at least for now - from a romantic perspective.
People: "Ariana Grande and Pete Davidson Split, Call Off Engagement: 'Too Much Too Soon, ' Says Source". "It's not shocking to anyone".
Neither Grande nor Davidson have commented publicly on the reports.
Ariana shocked fans back in June when she announced Pete had put a ring on it just weeks into their whirlwind romance.
Although neither Pete nor Ariana has confirmed a split, Pete has taken himself off social media. The singer has been lying low for some time now, though, as she processes not only Miller's death, but also the ongoing PTSD she has suffered since the bombing at her Manchester concert in 2017.
In a statement to People, her team said: "Given the events of the past couple of years, Ariana is going to take some much needed time to heal and mend". According to Us Weekly, she pulled out of an appearance at a cancer benefit scheduled for October 13 for personal reasons. Follow Yahoo Lifestyle on Facebook, Twitter and Instagram.
