PEOPLE confirmed the news.
"It’s a recent engagement. They’re just two people who found love quickly and make each other happy all the time. They both started talking about it this past weekend. It’s nothing they’ve been hiding," a source close to the couple explained.
After the news went public, Ariana Grande tweeted a pretty euphoric message.
"i love u sm ok bye."
The pair started dating very shortly after Ariana's break up with Mac Miller in May, and have been spamming their love for each other on social media ever since.
LOVE.IS.REAL. Pass it on.
