Abbey Lee ensured she was the centre of attention, as she slipped into two glamorous gowns to hop between red carpets on the final day of the Venice International Film Festival on Saturday.

The actress, 37, stunned as she graced the festival's closing ceremony in a black satin sleeveless gown which featured a diamante trim around the chest, after previously opting for a sheer lace look at the premiere of her newest film.

She put on a leggy display in her glamorous dress, which featured a daringly high split and black crystal detailing around the bodice.

Her garment was finished with a simple black bejeweled train.

To accessorise, she kept it simple with a short diamond necklace and a pair of dangly earrings.

Adding inches to her statuesque figure, she slipped into a pair of strappy metallic heels.

Her elegant appearance came hours after she stunned at the premiere of Kevin Costner's Horizon: An American Saga—Chapter Two.

The TV star left little to the imagination in a sheer lace dress as she joined her co-star Sienna Miller at the event.

She braless for the occasion as she stepped out in a nude bejeweled dress which featured a black lace bralette, a nude corset, and a slit up the leg.

Recycling some of her accessories, she opted for the same heels she picked out for her later appearance.

Adding something different to her ensemble, she styled her hair in two top braids. 

The 81st Venice International Film Festival is organised by La Biennale di Venezia and is being held on the Lido di Venezia from August 28 to September 7.

To close out the festival, Kevin Costner' Horizon: An American Saga - Chapter Two held its world premiere.

The film is the second chapter in a four-part saga, focusing on the American West during the late 19th century, and explores the vast and often tumultuous landscape of the nation's westward expansion.

The Horizon series is set against the backdrop of the Western frontier in the 1800s, focusing on the challenges and conflicts of America's expansion, with a specific look at the people who faced the hardships, uncertainties, and ambitions that shaped the nation.

It deals with issues like survival, indigenous struggles, personal and collective resilience, and the environmental and societal impacts of westward migration.

Each chapter will provide a different perspective on the historical period, weaving together personal stories against the greater backdrop of American history.

While details on Chapter Two's plot specifics have remained largely under wraps, it's expected to build on themes of conflict, adventure, and survival that are introduced in the first chapter.

The production of the films began in 2022, with Kevin leading an extensive team and shooting many scenes in rugged, natural landscapes across the U.S.

The new flick stars Kevin, Sienna Miller, Sam Worthington, Jena Malone and Michael Angarano.
