Vanessa Kirby and Julia Garner looked as glamorous as ever for the UK premiere of Fantastic Four: First Steps in London on Thursday.

The red carpet event precedes the release of the film in UK theaters later this month, with the eagerly awaited movie featuring Pedro Pascal and Joseph Quinn as well. 

Actress Vanessa, known for her role in Napoleon, aged 38, opted for a loose and frilly light blue dress that discreetly concealed her baby bump, as her blonde hair cascaded over her shoulders. 

Slipping into a pair of high heels, the actress looked utterly dazzling in the dress as she posed for photos on her arrival. 

While Julia, 31 – who shot to fame as Ruth Langmore in Ozark – matched her co-star in a similarly stunning blue dress.

The leading actresses posed for photos alongside fellow cast members, including director Matt Shakman, Ebon Moss-Bachrach, Pedro Pascal, Vanessa Kirby, Joseph Quinn, and Ralph Ineson (L-R). 

With her short blonde hair slicked to the side, the American star displayed a hint of her abs in the sweeping gown while sporting a matching blue bralette. 

The leading ladies posed for photos alongside their co-stars, including Pedro Pascal, Ebon Moss-Backhrach, Joseph Quinn and Ralph Ineson. 

And during a press event with MailOnline and other publications, the cast revealed the fun title of their group chat. 

‘It’s called ABBA,’ Pedro, 50, revealed. 

Before Vanessa chimed in: ‘We were brainstorming famous foursomes’.

Pedro then amusingly quipped: ‘I created it so they didn’t really have a choice’. 

Pascal – who plays the protagonist Mr. Fantastic in the blockbuster – seemed in great spirits on the night as he was seen bursting into laughter while posing for photos. 

The actor looked typically dapper in a baggy black suit while covering his eyes with a pair of orange-tinged sunglasses.

Keeping in tune with other cast members’ blue theme was Joseph Quinn, 31, who arrived at London’s South Bank in an eye-catching ensemble which he teamed with some black shoes. 

While Ebon Moss-Bachrach, 48, kept his outfit simple for the occasion, with the American actor undoing his top button underneath a simple black suit. 

After settling down inside the venue, the star-studded cast were treated to a performance from Myleene Klass, 47, who took to the stage alongside composer Michael Giacchino in the beaming London sunshine.

Produced by Marvel Studios, Fantastic Four: First Steps is intended to be the 37th film in the Marvel Cinematic Universe (MCU) and the second reboot of the Fantastic Four film series.

Directed by Matt Shakman, the movie sees the Fantastic Four protect their 1960s-inspired retro-futuristic world from the planet-devouring cosmic being Galactus.

At the movie’s German premiere on Wednesday, Vanessa Kirby looked every inch the stylish mother-to-be as she displayed her baby bump in a sleek black dress.

She teamed her fashionable, high-necked gown with towering black heels and dazzling silver drop earrings.

Vanessa first revealed she was pregnant with her child last month as she showed off her bump at The Fantastic Four photocall in Mexico.

Last December it was reported she was engaged to her boyfriend Paul Rabil after two years together.

The beauty, who starred as Princess Margaret in Netflix’s The Crown, was allegedly set to head down the aisle with lacrosse player love, 39, after he popped the question, according to Page Six.

MailOnline contacted representatives of Paul and Vanessa for comment.

Vanessa and Paul first sparked dating rumours walking hand-in-hand through New York City in October 2022. 

However, they didn’t make their romance Instagram official until November 2023.

At the time, American Paul – who is the co-founder of the Premier Lacrosse League – shared a series of photographs of the couple including one of them embracing on a beach.

‘From the very minute we first met in Des Moines, around the world and back, life is far better, more purposeful and more beautiful with you,’ he wrote about the film star.

The couple have been spotted on several occasions together since 2022, but had kept quiet about their blossoming romance.

Paul previously dated Mexican actress Eiza Gonzalez and was married to fellow sportswoman Kelly Berger, from 2014 until 2017.

In April 2022, Vanessa was linked to Christopher Abbott after the pair were spotted enjoying a drink at a trendy bar in London’s Soho.

The pair, who met when they played a married couple in 19th Century romantic drama The World To Come in 2020, were deep in conversation at Ducksoup.

An onlooker said the stars ‘looked super comfortable in each other’s company’ as they drank wine and chatted for a couple of hours at an outside table.

Vanessa previously dated Callum Turner after they starred in 2014’s Queen And Country.
