Kristen Stewart looks radiant and happy with co-star Nicholas Hoult as they attend Equals premiere at Venice Film Festival 

Kristen Stewart and Nicholas Hoult were rumoured to be a romantic item over a year ago.

The co-stars were certainly starry-eyed while cosying up together at the red carpet premiere of their futuristic love story Equals at the Venice Film Festival on Saturday.

Kristen, 25, leaned into the tall and strapping British actor while posing in front of the crowd of fans gathered at one of Italy's most illustrious celebrity events.

Indeed, the American star seemed to favour Nicholas, also 25, even when their director Drake Doremus joined them for a photo opportunity.

Kristen looked glamorous beyond words in a shimmery silver lace and satin gown that showed off her trim shins in front and dropped down in the back.

Shining silver pumps and a dramatic updo added to the effect, while vampish red lipstick brightened her pale and lovely complexion.

Make a mark in metallic

K-Stew might be famed for her love of skinny jeans, scruffy tees and trainers on her off-duty days, but she’s made quite a name for herself as a red carpet style icon.

The Twilight actress loves to switch up her red carpet looks with playsuits and skirts but we are loving the dress she wore to the Venice Film Festival.

Here, Kristen didn’t fail to impress yet again when she stepped out in a metallic silver lace overlay dress from Chanel Haute Couture Fall 2015 collection.

Sadly, the dress is unavailable but you do have the option to shop Chanel at Farfetch.com or take a look at our edit below to emulate Kristen's style.

We'll be pairing the Tadashi dress from Nordstrom with Christian Louboutin So Kate pumps to get that sooo cool look that Kristen has!

Nicholas was handsomely outfitted in a black tuxedo with black bow tie.

Kristen, who is usually stony-faced as such festivities, broke into smiles as she made her way down the carpet towards the venue.

And on Friday, Kristen and Nicholas sparked attention when they appeared cosy at a photocall to promote their film.

Posing alongside the film's director Drake Doremus at the Palazzo Del Casino, the pair looked extremely comfortable in each other's company as they stood side-by-side.

Their appearance at the Venice Film Festival - which runs through September 12 - came after they were reportedly seen 'cosying up' at a film bash in New York in October 2014.

According to Page Six, the two 'stuck together' all night during a Cinema Society event for Kristen's film Clouds Of Sils Maria, which was held at Omar's in New York City.

The party, also attended by the likes of Patti Smith, Juliette Binoche and Viggo Mortensen, served to fuel speculation that Stewart and Hoult were dating, despite denials from the actress.

X-Men: Days Of Future Past star Nicholas was in a relationship with Oscar-winning actress Jennifer Lawrence for three years until they split last year.

Meanwhile, Kristen and her Twilight co-star Robert Pattinson called it quits in 2013 after four years of dating.

Coincidentally, Liberty Ross announced on Saturday her engagement to music executive Jimmy Iovine - three years after her ex-husband Rupert Sanders cheated with Kristen.

Kristen and Rupert became close during the production of Snow White And The Huntsman, which Sanders directed.

Equals, meanwhile, is a dystopian remake of George Orwell's 1984 - it has yet to confirm a UK release date following its premiere at the Venice Film Festival on Saturday.

'I was nervous going into the movie because of how simple it is and overtly emotional. I’m 25,' Kristen said of the movie role, according to Deadline.com.

'I’ve been through some stuff and I knew it was going to be painful and I knew if I didn’t do it right I would have hated myself.

She said the hardest part of the filmmaking process was 'not allowing yourself to feel something. I wear my heart on my sleeve. If I’m in a mood, my mood shows.'
