One of our favorite divas Celine Dion is looking STUNNING in Paris, but fans are worried ...

The 51-year-old rocked a $4400 Chanel jumpsuit in the City of Lights, on Friday, but after a recent Instagram, Dionators expressed concern for the star's slender frame.

Celine answered by explaining she's doing intensive ballet practice, posting photos of her training and saying in a recent interview, "I do this four times a week. People say, ‘She’s a lot thinner’ but I’m working hard. I like to move and [weight loss] comes with it."

She looks happy and healthy to us and we say, more power to her!
