Lourdes Leon went braless in a racy sheer catsuit as she led the stars at Saint Laurent's Paris Fashion Week show on Tuesday.

The daughter of Madonna joined modest Zoe Kravitz and Iris Law at the glamorous catwalk at the Bourse de Commerce Pinault Collection.

The American singer, 28, left little to the imagination as she posed up a storm in the very skimpy ensemble.

Showcasing her enviable curves, she draped a chic black leather trench coat over her shoulders for a bit of modesty. 

The Lock&Key hitmaker further accessorised with a gold-toned necklace and matching hoop earrings, adding inches to her frame with black stiletto heels. 

Meanwhile, Zoe, 36, looked effortlessly chic in a beige one-shoulder dress with pleated ruffle detailing at the neckline, cuffs, and hem. 

She showed off her slender legs in sheer black tights, cinching her tiny waist with a chunky brown belt. 

The Batman star elevated her height with multicoloured pastel high heels as she posed for the cameras ahead of the show. 

While Iris, 24, commanded attention in a beige power suit, which featured a structured double-breasted blazer and flared tailored trousers. 

She paired it with a striped white shirt and a navy blue polka dot tie. 

To finish off the look, Iris added inches to her frame with pointed black heels and accessorised with a stack of chunky gold bangles and hoop earrings. 

It comes after Lourdes was gunning to play her mother in the singer's upcoming biopic, but lacked the acting experience needed to take on the Material Girl. 

The film, currently titled Who's That Girl, is finally in the works, four years after a script was completed and nearly two years after it was put on hold while Madonna embarked on her Celebration tour.

Lourdes, aka 'Lola', was considered, but lost out on the role to actress Julia Garner, who was in a two horse race with Kathryn Newton, with Madonna and film bosses struggling to make a decision on who should play the Queen of Pop.

'Lola was being considered for the role of her mom, but she did not have the acting experience necessary to play such a difficult part,' a source told DailyMail.com exclusively. 

Who's That Girl - a reference to Madonna's 1987 comedy film and single of the same name - is set to chronicle her decades long career, as well as aspects of her personal life, including her relationship with Carlos Leon, 58, and the birth of their daughter Lola in 1996. 

Carlos had been championing Lola for the role, claiming she was the perfect casting to play the boundary-pushing singer. 

'I hope they cast a gorgeous baby to play Lola because she was as beautiful then as she is now,' he told DailyMail.com in August. 'They need to hire an actress who gives off strength, it’s in her blood.'

'Lola is a phenomenal actress I think she would be great.'

Julia, 30, and Kathryn, 27, had undergone screen tests for the role and took part in an intense 11-hour audition process with the singer's choreographer. 

They were also required to take part in several script readings with Madonna and had to perform her songs in front of her.

Julia, who played con artist and fraudster Anna Delvey in Netflix hit Inventing Anna, previously revealed she prepared for the role by studying Madonna's music, performances, and personal life.

She also joined Madonna onstage during her Celebration Tour in Brooklyn, New York in December 2023. 

Lola recently opened up about her career and said she would consider acting if she was presented with a role not 'too far off' from who she is.

'I don't have a specific goal. I probably should,' she told her mom's lifelong friend Debi Mazar for Interview magazine.'

'Financially, modelling is a smart decision. I enjoy being very hands on with the campaigns I do, so that I'm not just modelling, per se.'

'I dance, I have a very specific sense of style, and I'm interested in aesthetics, so I like to incorporate all those parts of myself into my projects.'

She continued: 'I don't know how I feel about acting yet. I think it's about finding a role that wouldn't be too far off from who I am already.'
