Ariana Grande wished a very special Arianator happy birthday on Wednesday night, when she shared a touching tribute for Saffie Roussos, the youngest victim of the May 22 bomb attack in Manchester.

Roussos, who was killed in the attack, would have turned nine on Tuesday, July 4. On July 5, the singer shared a photo of herself performing on her Dangerous Woman Tour, writing in the caption (alongside a birthday cake emoji), "Saffie, we're [thinking] of you baby."

The young Ariana Grande fan was one of 22 people killed when a suicide bomber detonated an explosive outside of the Manchester Arena following the conclusion of Grande's concert on May 22.
