Eva Longoria flaunts her sensational curves in figure-hugging white gown as she attends the 69th Cannes Film Festival Opening Night Gala premiere of Cafe Society

She's undoubtedly one of the most fashionable celebrities in the industry.

So, continuing to reign supreme as style queen, Eva Longoria turned heads once again as she attended the premiere of Woody Allen's new film at the Cannes Film Festival on Wednesday.

The 40-year-old beauty - who's engaged to TV mogul Jose Antonio Baston - was hard to miss, flashing her curves at the red carpet launch of Cafe Society at the Palais des Festivals et des Congrès.

The sizzling number, which featured a spiked mesh upper design, highlighted her sculpted limbs and toned curves perfectly.

Flashing her pearly whites as she worked her magic in front of the cameras, the Desperate Housewives star enhanced her complexion with dramatic eyewear and glossy lips.

She accessorised her sexy getup with gold flakes which she wore on her eyelids for extra dramatic effect, while sporting diamond and ruby encrusted stud earrings, while wearing her brunette tresses in cascading waves.

Posing up a storm on the red carpet, she was clearly on fine form - and worked the trail on her dress to ensure it perfectly showcased her Kim Kardashian-esque silhouette.   

Clearly delighted to be at the launch of Woody Allen's 49th film, which is his third to have opened the festival, after Hollywood Ending in 2002 and Midnight in Paris in 2011. 

His new film brings Kristen Stewart and Jesse Eisenberg together on screen for the third time, after 2009's "Adventureland" and last year's "American Ultra".

Eisenberg's character leaves New York City for Hollywood, hoping his impresario uncle, Steve Carrell, will give him a break. His eye is taken by Stewart, but he has to settle for friendship until she comes to tell him her lover has left her. 

As in many of his films, there is a lot of Allen himself in the protagonist of Cafe Society.

If this was years ago, I would have played this part much more narrowly myself because I'm a comedian, not an actor. Jesse gave it much more complexity,' Allen said.

Stewart said the film was 'immediately recognisable' as a Woody Allen, 'Once we got going, that tonal quality that's so familiar and immediately recognisable, it just happened,' she said. 

'I think we kind of nailed it.'

Meanwhile, Eva has been busy working on her latest project, drama series Telenovela, which sees her play Ana Sofia Calderon in the American sitcom.

The network ordered 11 episodes in October (having cut its order from 13) and the final episode in the season will air on February 22. It is not yet known if the show will be renewed for a second season. 

During an appearance on the Wendy Williams Show last month, she said: 'If you liked Gaby (her character on Desperate Housewives) - and everybody liked Gaby - you will love Ana Sofia. Cause she's crazy. She's like ten times crazier.’

The star also dished the details on her recent engagement, by saying: 'It was such a surprise. It was in Dubai and it was in the desert. We're still absorbing that moment.’

This will be the third marriage for Eva, who filed for divorce from basketball star Tony Parker in 2010 following three years of marriage - she was previously married to General Hospital actor Tyler Christopher from 2002 to 2004.
