So, the couple took the stage together for a “Best Mistake” duet, a track off Grande’s 2014 album My Everything.
As if that wasn’t enough, the couple also gave the Detroit crowd a show when they kissed on stage, a candid look at the love birds who were once quite private about their romance.
Before the show, Ariana gave us a hint about the surprise performance when she posted a picture with Sean.
“With my baby in the D #detroit #duh #NottheonlyDtho #what #gottagobye,” she said in the caption.
After the show, Ari thanked Sean for coming through.
And to think...It was a huge deal when we first saw them holding hands.
Their latest cut together is "Research" and while it's not about them, the song is yet another example of their chemistry.
Something tells us we'll be getting more Grande-Sean collaborations soon.
