She was recently spotted enjoying the breathtaking sights of Venice as she and her film-maker beau, Darren Aronofsky, enjoyed a boat ride through the Italian city’s famous canals.

But on Tuesday afternoon, Jennifer Lawrence was in work mode as she was spotted out and about at the star-studded 74th Venice Film Festival, looking stylish in two strikingly different ensembles.

The 27-year-old actress was first seen making her stylish arrival at Hotel Exelsior in a quirky pair of checked trousers before later attending a photo call in a plunging lace maxi gown as she promoted her new flick, Mother!, with the film’s director and her boyfriend, Darren Aronofsky.

The Silver Linings Playbook star Jennifer looked casually cool as she disembarked a water taxi in her first ensemble of choice, which included vertiginous black heels featuring bold gold accents.

Shielding her eyes from the early autumn sunshine with a pair of circular-framed Oliver Peoples shades, her blonde tresses were styled in bouncy, voluminous waves, while an array of gold jewellery added a touch of pizzazz to her look.

However, proving her show-stopping sense of style on more than one occasion, Jennifer later changed into a saucier lace maxi dress as she arrived at the photocall itself.

The stunning frock by Giambattista Valli Resort was incredibly summery and feminine with its pastel pink hue, but was made more Gothic in style by its striking black lace overlay.

Cascading all the way to the floor in a full maxi skirt, the gown was then made far saucier by its daring plunging neckline, which extended all the way to her waist to give an eye-popping flash of her cleavage underneath.

Drawing further attention to her bust with a silver pendant, Jennifer effortlessly tied her look together with the same trendy round sunglasses and added a more glamorous curl to her hair for the official promotional event.

Clearly excited for a day of promotion, Jennifer cut a radiant figure as she beamed widely for cameras and waved at adoring fans patiently awaiting her arrival by the water.

Also seen stepping out on the day was Michelle Pffieffer, who effortlessly oozed glamour in her eye-catching plunging dress, which she teamed with a pair of black textured suede heels.

With a black blazer slung over her shoulders to stave off the possibility of any chill from her boat journey, the veteran screen star’s golden locks rested about her shoulders in a bombshell blowout.

Wearing a pair of oversized sunglasses, Michelle waved at onlookers as she went about her day ahead of another busy roster of events at the glitzy gathering, which has attracted a host of A-list stars.

However, like Jennifer, the beauty also swapped into another ensemble for the photocall, slipping her svelte frame into a form-fitting floral dress.

The frock was utterly sophisticated, with a high neck and long sleeves, but 𝓈ℯ𝓍ily accentuated her envy-inducing figure by cinching in at her petite waist and hugging her frame all the way down.

Patterned with a colourful floral print of pink and blue, the dress was then made more striking by its drop hem, which billowed out into soft pleats at her calf.

The actress tied her look together with strappy black court shoes and a classically chic wavy blow-dry, which she swept away from her face to draw attention to her radiant and youthful complexion as she posed.

The girls were joined by their co-star Javier Bardem at the photo call, as well as the film’s director, Darren Aronofsky.

Shortly after arriving in Venice over the weekend, Jennifer and Darren were seen enjoying a boat ride through the historic canals of the stunning city.
