The 20-year-old singers confirmed the news on Twitter after they were spotted out together in Toronto last month.
“we hesitated saying anything as people can be a bit insensitive but thank u we value all of your happiness, thank you for valuing ours <3 :)" Ari tweeted.
Nathan followed that up with, “So, I guess it’s obvious now…thanks to everyone who is being so lovely. I’m so happy <3 #butweareterrified #pleasedontkillme #orariana"
WHAT DO YOU THINK of Ariana and Nate as a couple?
