Elle Fanning oozed glamour in a plunging blush gown as she lead the stars at the Cannes Film Festival premiere of The Mastermind. 

The A Complete Unknown star, 27, was among the Hollywood stars who took to the red carpet for the premiere of the film, starring Josh O'Connor and Alana Haim, on Friday.

Elle, the sister of fellow actress Dakota Fanning, looked sensational as she stepped out in a long-sleeved blush pink gown, which was adorned with jewels and featured a plunging neckline. 

Her geometric patterned gown also had a train at the bottom of its tulle skirt and a brooch attached to the waistband, with her blonde locks in natural waves. 

She was joined on the red carpet by Bridgerton star Simone Ashley, who turned heads in a white puffed out strapless midi dress complete with statement features at the bust.

Simone, 30, looked effortlessly chic in the ruched gown, which cinched her in at the waist, and she paired it with white stilettos and diamond drop earrings.

Another star who was spotted out at the festival on Friday was Gillian Anderson, who wowed in a green gown.

The Sex Education star, 56, looked sensational as she stepped out in a spring green jacquard print gown, featuring a full skirt and a small waistband, as well as thin straps.

Gillian's blonde locks were swept into a beehive messy bun and she paired the dress with Swarovski Created Diamonds.

Meanwhile Michelle Keegan also made an appearance as she stepped out in a structured white gown and a dramatic hat ahead of the L'Oreal Light on Women Award.

The former Coronation Street star, 37, was seen at Hotel Martinez on Friday during day eleven of the Cannes Film Festival before attending the premiere of The Mastermind.

Michelle turned heads as she stepped out in a stunning white corseted strapless gown, which featured a peplum design and figure-hugging skirt. 

She paired the gown with a striking matching hat and open-toed satin heels, accessorising with a statement diamond necklace. 

The stars of The Mastermind were also out in force as The Crown's Josh joined his co-star, HAIM band member Alana, on the red carpet.

The L'Oreal Light on Women Award 'champions emerging female voices in film' and will this year be hosted by American actress Viola Davis, 59, who follows in the footsteps of Elle Fanning and Kate Winslet. 

The L'Oreal award will be handed out to one standout female director from the Cannes Short Film Competition after Viv Li scooped the prize for her work on Across the Waters in 2024. 

The event comes on the penultimate night of the festival after a host of A-listers flocked to Cannes over the previous couple of weeks. 

Filmmakers come from nearly every corner of the globe to showcase their films while dealmakers work through the night to sell finished films or packaged productions to various territories.

The awards were being held as part of Cannes Film Festival, which will come to an end on Saturday with a closing ceremony. 

Cannes, where filmmakers, sales agents and journalists gather from around the world, is the Olympics of the big screen, with its own golden prize, the Palme d´Or, to give out at the end. 

'You release a film into that Colosseum-like situation,' says Brazilian director Kleber Mendonça Filho, who´s returning to Cannes with 'The Secret Agent, a thriller set during Brazil´s dictatorship. 

'You've got to really prepare for the whole experience because it´s quite intense - not very far from the feeling of approaching a roller coaster as you go up the steps at the Palais.'

This year's Cannes Film Festival is taking place in the wake of Trump´s vow to enact tariffs on international films. 

Trump sent shock waves through Hollywood and the international film community when he announced on May 4 that all movies 'produced in Foreign Lands' will face 100 percent tariffs. 

The White House has said no final decisions have been made. Options being explored include federal incentives for U.S.-based productions, rather than tariffs. But the announcement was a reminder of how international tensions can destabilise even the oldest cultural institutions.

The Cannes Film Festival originally emerged in the World War II years, when the rise of fascism in Italy led to the founding of an alternative to the then-government controlled Venice Film Festival. 

In the time since, Cannes´ resolute commitment to cinema has made it a beacon to filmmakers. Countless directors have come to make their name.

This year is no different, though some of the first-time filmmakers at Cannes are already particularly well-known. 

Kristen Stewart (The Chronology of Water), Scarlett Johansson (Eleanor the Great) and Harris Dickinson (Urchin) have all unveiled their feature directorial debuts in Cannes´ Un Certain Regard sidebar section.

Many Cannes veterans have returned, including Tom Cruise (Mission: Impossible - The Final Reckoning), Robert De Niro - who received an honorary Palme d´Or 49 years after Taxi Driver premiered in Cannes - and Quentin Tarantino, who paid tribute to low-budget Western director George Sherman.

Over recent years the star-studded extravaganza has arguably won more attention for the outfits worn by its celebrity guests than the roster of feature films being screened on the Croisette. 

But new nudity rules, devised for 'the sake of decency,' have been implemented at this year's festival.  

According to organisers, the austere move is an attempt to stifle the celebrity trend for 'naked dresses' - namely provocative outfits that reveal considerably more than they conceal - on the red carpet.

'For decency reasons, nudity is prohibited on the red carpet, as well as any other area of the festival,' states a Cannes festival document.

'The festival welcoming teams will be obligated to prohibit red carpet access to anyone not respecting these rules.'
