Alexa… attend something French: TV presenter Chung stuns in a plunging black gown at the Cannes premiere of Sienna Miller’s Horizon: An American Saga – weeks after ‘secret engagement’ to her ex Tom Sturridge

Alexa Chung wowed in a skimpy black dress as she arrived at the 77th annual premiere of Horizon: An American Saga at the Cannes Film Festival on Sunday, weeks after a rumored engagement to the leading lady’s ex-boyfriend.

The model, 40, showed off her incredible figure in the racy black number with a plunging neckline as she made her way down the Croisette.

Alexa dressed up tastefully in some dark shades and flashed a bright smile as she made her latest appearance on the red carpet.

She completed the overall look with a simple black and white bracelet on her right wrist and topped it off with a simple pair of high heel sandals.

In terms of makeup, the former MTV star kept the thighs natural with just a hint of blusher and let her tousled dark locks hang neatly around her shoulders.

In other photos, the TV presenter was seen striking a sultry pose as she flipped her dark hair after removing her sunglasses.

Other stars who graced the red carpet included Julianne Moore, who was effortlessly elegant in a fitted green dress with a seductive ruffled neck detail.

The film – starring Kevin Costner and Sienna Miller – chronicles a multifaceted, 15-year period of expansion and settlement of the American West before and after the Civil War.

Alexa attended the event following a reported engagement to boyfriend Tom Sturridge, Miller’s former partner and father of her young daughter Marlowe, who also attended on Sunday.

The model first sparked engagement rumors with the actor, 38, in June, with the pair wearing matching rings in October.

Now the couple are said to be ‘over the moon’ and are planning a ‘stylish’ wedding ceremony in the summer.

A source told The Sun: ‘Alexa has confirmed to her friends that she is indeed engaged to Tom and is over the moon.

“She’s in a great place and seems completely in love with him. They are a great match.’

Cannes is the world’s largest film festival, first conceived in 1939 as an alternative to the then fascist-influenced Venice Film Festival.

It has been held annually since 1946, except in 1948 and 1950, when it was canceled due to lack of funds.

The festival is known for its carefully selected program of films that achieved Oscar success or launched the careers of directors such as Quentin Tarantino.

Cannes’ top prize is the Palme d’Or, or Palme d’Or, whose previous winners include Taxi Driver, Apocalypse Now, Pulp Fiction, The Pianist and Parasite.

The Cannes Film Festival officially kicked off on Tuesday evening as celebrities walked the red carpet to the luxurious Grand Theater Lumiere in honor of Hollywood actor Meryl Streep before settling in to watch this year’s opening film, The Second Act..

Artists from all over the world who have made a name for themselves in their field are chosen to serve on the jury, with one member appointed as jury chairman.

This year’s jury chairman, American director Greta Gerwig, comes to Cannes after the huge success last summer of Barbie.

She is the first female American director to serve as jury president, taking over from the head of the 2023 jury, Triangle of Sadness director and two-time Palme d’Or winner Ruben Ostlund of Sweden.
