The highly-acclaimed Martin McDonagh was supposed to be the star of the show at the premiere of his film Wild Horse Nine at Venice Film Festival tonight.

But it was his actress wife Phoebe Waller-Bridge who caught the eye as she made a rare public appearance alongside him on the red carpet.

Wild Horse Nine stars Parker Posey, John Malkovich, Sam Rockwell and Steve Buscemi. It marks McDonagh’s return to directing since his acclaimed 2022 film The Banshees of Inisherin earned a string of Oscar nominations. 

Waller-Bridge, 41, made a show-stopping arrival head to toe in custom Celine to support her Oscar-winning partner, 55.

McDonagh complemented Waller-Bridge’s trousers and white cape with a simplistic black suit, also from the designer brand.

The couple have been dating since 2017 and sparked rumours a wedding was on the cards back in 2023. 

Waller-Bridge flashed a huge diamond ring on her engagement finger as she posed for pictures at the premiere. 

Laura Dern, Leslie Bibb, and models Kendall Jenner and Stella Maxwell brought the glamour in dazzling glitzy gowns as they made their show-stopping entrance.

Jenner, 30, showed off her model physique in a vintage Giorgio Armani dress from the brand’s 1995 collection.

She was joined by fellow fashion favourite Maxwell, 36, who opted for a revealing black lace gown. 

Hollywood actress Dern, 59, oozed elegance in a sequin gown for day two of the festival.

Meanwhile, Parker Posey, 57, looked age-defying in a plunging white cape dress. 

Leslie Bibb, 52, displayed her toned legs in a navy and black thigh-high split dress as she larked around with her long-time partner Sam Rockwell. 

The film is set in 1973, shortly before the Chilean coup, and sees CIA officers Chris and Lee dispatched from Santiago to Easter Island by their bureau chief, MJ. 

Amongst the Island’s iconic statues, and as the longtime partners wrestle with their dark pasts and present conspiracies, Chris’s newfound bond with a pair of rebellious students threatens to send everyone’s trip to this remote paradise sideways.

The film is set to compete for the coveted Golden Lion Award, and will be released theatrically on November 6.

Waller-Bridge and McDonagh are considered one of the film world’s most prolific power couples.

The actress has been hand to celebrate her partner’s successes, including the Oscars in 2023, where his film The Banshees Of Inisherin was nominated for nine awards.

‘It’s really useful being with someone who I think is a genius, it just ups your game,’ she previously said of her relationship.

Waller-Bridge has had a very successful decade with her career, finances, as well as in her love life.

According to Companies House, her company, PMWB Limited, made nearly £16million in the financial year ending last November.

She has also won Golden Globes, Emmys and a BAFTA for smash hit Fleabag and has been nominated for her work writing and producing Killing Eve.

Waller-Bridge made her acting debut in 2009 at the Soho Theatre and first introduced the world to Fleabag back in 2014 when it was a one-woman show at the Edinburgh Festival.

She got her first shot at fame in 2015, starring in the second series of ITV drama Broadchurch as junior barrister Abby Thompson.

But she catapulted to fame in 2016 when the first series of Fleabag aired on BBC Two.
