Yah, we're shocked too.
The couple has only been together for a few months and just recently made it Instagram official, however, it seems like things are pretty serious for the stars since they've apparently decided to get married.
Us Weekly was the first to report that Grande and Davidson are planning to get hitched, saying that multiple sources confirmed the good news. Despite the shockingly swift engagement, according to Us, the couple isn't sprinting down the aisle just yet.
"They are looking forward to a very long engagement together," a source said.
The "No Tears Left Behind" singer and the "SNL" star got together in May shortly after Grande's break up with rapper Mac Miller.
