The style expert, whose roster also includes Bonang Matheba, Zendaya and Ariana Grande, has been working with the Think Twice songstress for over a year, with fans taking note of the Canadian superstar's new look.

Celine is no stranger to couture and has been stepping out in everything from Stephane Rolland gowns to a faux leather Givenchy number, and Law claims that comfort never comes into her choices.

"She’s the true embodiment of a fashion girl," he told The Cut. "She will make it work for the look. She’s just the quintessential diva. She’ll sacrifice her body and endure pain for a beautiful look."

During Couture Fashion Week in Paris in July (17), Celine stepped out in ruffled Giambattista Valli minidress for the brand's show, and wore a mustard yellow belted gown to the Christian Dior presentation.

While the 49-year-old can pull off just about any outfit, Law thinks she looks best in simple denim.

"I love her body in jeans. Like, she has amazing long legs and a small waist, so she actually wears jeans really, really well. And sometimes jeans and a T-shirt is way sexier than a low-cut blouse or a skirt with a high split," he shared.

Celine and Law have had plenty of fashion moments since they began working together, especially when he dressed her in a Titanic-themed Vetements sweatshirt. But the stylist has his sights set on another groundbreaking fashion moment.

"Because one of her most infamous style moments happened at the Oscars, I would love to have an Oscars moment with her,” he admitted. “I loved that backwards Galliano suit (she wore to the 1999 ceremony); it was before it’s time."
