The 23-year-old posted a photo of the Eiffel Tower on Instagram with the caption, "First show back tonight. Thinking of our angels every step of the way. I love you with all my heart. Grateful for and incredibly proud of my band, dancers and entire crew. I love you I love you."
The pop superstar added her new charity single "Somewhere Over the Rainbow" to her set, which raises money for the victims of the tragic attack.
Following her performance, Ariana said: "Merci, Paris. Je t'aime. Grateful to be back;' with Arianators quick to show support.
On her Instagram, one commenter said, "Such a strong woman" and another said, "You're so perfect, and I love you for your voice, your generosity, and your kindness."
Ariana's tour continues in Portugal, Spain, and Italy next week.
