Ashley Roberts, while battling the muggy August weather, suffered an awkward fashion faux pas as she struggled to keep cool in her skintight grey dress.

As the TV personality, 42, she posed for her snaps, her armpits become noticeably sweaty due to the humid weather.

Nevertheless Ashley brushed off the blunder as she exuded confidence in her eye-catching grey dress, teamed with silver strapped heels and a white clutch bag.

The movie is set between the original 1979 classic Alien and the 1986 sequel Aliens, telling a brand new story within the franchise.

While the full reviews aren't in quite yet, social media reactions from several critics across the country have started flooding in on X (formerly Twitter).

Many of them praise writer-director Fede Alvarez (Evil Dead remake) for film, insisting that it isn't full of 'fan service' like many new franchise films are.

One critic - The Hollywood Reporter's Borys Kit - even claimed that the film takes the 40-year franchise, 'in a crazy new direction.'

'Alien: Romulus: Has all the great hallmarks of what you would expect in an Alien flick but never feels like it’s pandering to nostalgia or fan service…and even goes into a crazy new direction. Fede Alvarez & the cast just gave birth to summer’s best movie,' Kit tweeted after attending the film's premiere.

Variety's Jazz Tangcay added, '#AlienRomulus The b***h is back. Was skeptical going in, but this is easily one of the better films in the franchise.'

Fede Álvarez doesn't disappoint. Awesome sound design and world-building. The practical effects are so good that the film gave me nightmares,' she added.

MovieWeb's Richard Fink tweeted, 'I really dug #AlienRomulus! It’s a gory monster movie with some truly inventive set pieces. Act 3 had me gasping in horror.' 

Alien: Romulus's trailer begins with a space ship flying towards a space station, along with glimpses of the seemingly-abandoned space station.

The opening shots are very reminiscent of the opening moments of Ridley Scott's original Alien.

As the camera moves throughout the space station, we can faintly hear people talking... as the conversations get more and more intense.

The camera then pans to a pod of some sort, which is covered in blood as we can hear a woman screaming. 

A male voice is heard saying simply, 'Run,' as we see the iconic Facehugger creatures from the original chasing after a character.

There are also several shots of people walking or running, though there are only brief glimpses of their faces.

We ultimately get better looks at Andy, Kay and Rain, plus another shot of a Facehugger finding a new victim.

The final shot offers a close-up look at Rain, intensely surveying her surroundings with a huge gun, before she looks up and the iconic Xenomorph opens its jaws.

Director Fede offered some more insight into the highly-anticipated film in a new interview with Variety, including when exactly the film is set in the 57 years between Alien and Aliens.
