Eva Longoria revealed far more than she intended too as she turned out for the star-studded and rained upon screening of Jimmy P. Psychotherapy Of A Plains Indian during Cannes Film Festival on Saturday.

And Rosario Dawson suffered similar fate as she attended the As I Lay Dying premiere in the French City on Monday night.

But thankfully the Sin City star was wearing white underwear when her stunning white Elie Saab gown parted at the front split to reveal all on those infamous Cannes red carpeted stairs.

The 34-year-old let out a little shriek when she realised the wardrobe malfunction and quickly pulled  the fabric across her thighs.

Rosario earlier flashed plenty of leg in the daring dress, which was slash to the thigh, without consequent.

The delicate embellished gown also featured a low-cut to further reveal her decolletage.

The actress wore her hair in Heidi-style plaits for the event and she accessorised with white stilettos, a cream and gold clutch and a stunning strand of diamonds.

Eva suffered the mother of all embarrassing wardrobe malfunction at Cannes over the weekend.

Arriving at the screening of Jimmy P. Psychotherapy Of A Plains Indian in a breathtaking light green gown, Eva was merely trying to ascend a flight of stairs while avoiding the fast-falling drizzle.

 

She tugged up her hem to avoid getting it wet in the puddles when the wardrobe function occurred as the star was left exposing herself with no underwear on.

Eva, 38, was no doubt horrified to learn that the humiliating incident was caught on camera.

The former Desperate Housewives star trudged on with the aid of several red carpet staffers and was ultra careful not to step on her trailing gown with her beige high heels.

 

Meanwhile, star of As I Lay Dying Ahna O’Reilly wore a pair of matching scarlet trousers underneath her Monique Lhuillier dress as she attended the premiere of her film on Monday night.

Ahna stood out in her stunning red dress which featured an intricate lace design and uneven hemline.

Underneath the attire was some matching red tulle which acted as a lining to the gown.

 

Ahna accessorised the ensemble with some champagne satin sky high Ferragamo heels and large H. Stern diamond drop earrings.

The American star wore her auburn tresses in a plaited Heidi-style and had lashings of red lipstick on her pout.

Ahna, who is best known for her role in the Academy Award winning film The Help, cuddled up to Franco as they posed for pictures on the red carpet.

James, 35, meanwhile looked dapper in a black tuxedo as he draped his arm around Ahna and fellow American actress Beth Grant, who also stars in the film.

Earlier in the day James and Ahna had been busy promoting their film at a photo call.

This time James wore a navy suit, white shirt and matching navy tie and Ahna is wearing a Marni dress and Bionda Castana shoes.

 

 

James is in Cannes to promote his new film As I Lay Dying, which he also directed.

The drama stars Ahna and Logan Marshall-Green and has been selected in the Un Certain Regard section of this year’s festival.

James’s Cannes appearance came after he wrote a piece defending Baz Luhrman”s film adaptation of The Great Gatsby to critics.

Of course, the Spring Breakers actor is well qualified to critique it as he was a PhD student in English at Yale and has taught English classes at NYU in New York.

He wrote in Vice magazine: ‘It was similar to what Walter Salles faced with On the Road: how to stay loyal to the era depicted, while still retaining the rawness of the original text.

‘We allow the classics to get away with so much because we love the characters. But when older stories are revived for film, the issue of the past and present must be rectified.

But that lack was not a function of anything missing in the actors or the general direction as much as it is a result of the passage of time, the encasing of a book in the precious container of “classic” status.’
