She wrote, "w my baby in [Detroit]."

Instead of just watching from the sidelines, he also joined her on stage, performing his part in "Best Mistake."

It makes sense, though. If he's there, why not rap his part in the song? But it's also just another super-cute example of him supporting his girlfriend and showing how much he cares about her career. After all, that was one of the reasons they fell in love!

Do you think it's sweet that Sean visited Ariana? Tell us in the comments!
