The superstar was greeted by her loyal fans - famously called Lambily – in the French city on Wednesday (10 June).
But she didn't get to make a quiet exit, as it seems everybody wanted to grab a selfie with the star!
And we're totally not surprised...it is Mariah, after all!
The mum-of-two happily posed for photos, and fans were desperate to get a glimpse of the 'We Belong Together' singer.
Mariah, 45, left the hotel in a black maxi dress, which she teamed with a cropped leather jacket and embellished heels.
She was in Paris to promote her new album, #1 To Infinity, which is a collection of her greatest hits.
The compilation album, which features 18 of her No.1 singles, also features her new track, 'Infinity'.
