The singer, however, eventually split from David, and now she is opening about their short-lived romance.
The singer is featured on the cover of American Vogue along with her model dog, Toulouse, for the August issue.
Talking to the magazine for her cover story, the 26-year-old singer revealed she initially did not know Davidson. Ariana admitted their romance was highly unrealistic and merely an 'amazing distraction.'
The singer further explained it was probably a summertime last year, her friends invited her to New York for some fun time; that's where the singer met Pete and found him as a fantastic distraction.
"Then, I met Pete, and it was an amazing distraction. It was frivolous and fun and insane and highly unrealistic, and I loved him [Pete], and I didn't know him. I'm like an infant when it comes to real life and this old soul, been-around-the-block-a-million-times artist. I still don't trust myself with the life stuff.", Ariana Grande shared.
Though Ariana's engagement to Pete did not last very long, the singer said being with him made her happy.
