Olivia Culpo unveils her ample cleavage in a striking black and purple dress at the Cannes Film Festival premiere of Asteroid City

Olivia Culpo turned heads when she revealed her plunging neckline in a daring gown as she posed at the premiere of Asteroid City at the Cannes Film Festival on Tuesday.

The model, 31, turned heads in the striking black and purple gown as she created a storm at the star-studded event.

She showed off her incredible figure in the long-sleeved garment that boasted a black velor top with an extreme center cutout that showed off Olivia’s ample cleavage.

The glamorous ensemble’s skirt flared out to the beauty’s hips in a huge purple pleated train.

Olivia turned up the heat and applied a flawless makeup palette, including a bold smokey eyeshadow and a perfect winged eyeliner.

The former Miss Universe winner wore a pair of simple silver hoop earrings.

She completed her red carpet outfit by pulling back her long dark brown locks from a center parting into a neat low bun.

Directed by Wes Anderson, the film follows the route of a Junior Stargazer convention that is spectacularly disrupted by world-changing events.

Asteroid City stars actors such as Jason Schwartzman, Scarlett Johansson and Tom Hanks.

The outing comes after the former beauty queen became engaged to NFL running back Christian McCaffery, 26, last month while vacationing at Utah’s Amangiri resort.

The beauty queen and Christian have been dating since May 2019.

Olivia shared the news of her engagement on Instagram, sharing black and white photos of the special moment. White flowers in tall vases could be seen in the background.

The model captioned the post: “4-2-23” and added an infinity emoji on either side of the date.

The San Francisco 49ers running back got down on one knee when he asked his brunette bombshell love for her hand in marriage.

Olivia’s ring is a custom engagement ring designed with Ring Concierge.

“We worked with Christian to design a ring that encapsulates Olivia’s trendsetting style while remaining timeless – a beautifully cut oval flanked by side epaulettes set in a handmade gold and platinum setting,” said Nicole Wegman, founder and CEO of Ring Concierge to DailyMail .com.

Christian – who was born Jackson McCaffrey – is an American football running back for the San Francisco 49ers of the National Football League.

He played college football at Stanford and was drafted by the Carolina Panthers eighth overall in the 2017 NFL Draft.

Recently, Olivia was seen in Mexico with Christian. They enjoyed the warm weather during their seaside holiday while spending time on a yacht and also playing a round of golf.
