Stepping out from her hotel into Paris streets on June 29, Celine Dion wore a coat thrown open over an Off-White leotard originally modelled by Gigi Hadid and blue-and-black heels. And that was it. No pants.

“I love fashion a lot. It’s a way of expressing yourself,” Dion told Elle in January.

“When I put something on, I play. I don’t take myself seriously. I kind of, like, borrow a character.”

Or steal a mantle. Once a fashion punchline, the singer, 51, ruled as undisputed style queen during Paris Couture Fashion Week, taking down A-listers including Gwyneth Paltrow, Margot Robbie and Shailene Woodley.

Nicole Kidman resorted to her signature move of kissing husband Keith Urban to drag attention away from Dion, but was still totally out-Celined.

Her epic fashion marathon confirmed the Canadian mother of two’s metamorphosis into the world’s most unexpected fashion icon. Her rebirth was personal: In 2016, she returned to Paris for the first time in 11 years after the deaths of husband Rene Angelil and brother Daniel.

Now, “No one” does the French capital’s most important week like Dion – who screams support for designers and weeps at beautiful pieces – said Glamour magazine.

“She lives, she breathes the fashion—stopping to pose, giving multiple angles to onlookers, and just having the best goddamn time.”

Even her outfit just to do some shopping made headlines when Dion wore an open-sleeved blazer, black mini and Vetements ‘I heart Paris Hilton’ T-shirt with a Titanic ‘Heart of the Ocean’ necklace.

Mixing irony and a stonking ugly gem is something best left to professionals, and Dion has help from her constant companion, back-up dancer turned stylist Pepe Munoz and Sydney Lopez.

Still her confidence is all her own, and Dion – who built time into her European tour to own Paris – showcased that when she arrived in the City of Light in Chanel’s black capri catsuit with a logo-hardware belt.

Later that day, Dion teamed a feathered pink Attico top with Ksenia Schnaider jeans (with one flared leg, one straight) and an F-covered Fendi bag.

Then she took in Miu Miu’s 2020 cruise collection at a club wearing a strapless, ruched fuschia gown with giant black bow that will have everyone running to their local dressmaker with a bolt of taffeta.

Exploring Paris, Dion’s tourist outfit was an 1980s-inspired Ronald van der Kemp dress with a black-and-white tuxedo jacket top and yellow tutu skirt, worn with mismatched Jimmy Choos.

For her first official event at Schiaparelli, she wore a custom black halter dress with elbow-length gloves by the house’s creative director Daniel Roseberry with Stephen Jones structured headpiece and shoe boots.

For her next trick, Dion hit up Iris van Herpen in a red and black 3-D printed gown by the Dutch designer.

On July 3 the Grammy winner kept up the astonishing work at Alexandre Vauthier in an ivory mini dress with exaggerated balloon sleeves that doubled as trains.

For Valentino, she switched up her ironed hair for waves and paid homage to the Italian house in a white feathered sequin mini dress.

For all the accolades, Dion threw up her hands when Elle asked about her icon status.

“I don’t know, I just do one day at a time, do the best I can, feel the way that I want to feel. That’s the most important thing.”

Dion told The Sun she’s “at the best of my life” now.

“I really want to enjoy and embrace every moment of it. It’s all new. It’s like I’m having a second wind.”
