Rosie Huntington-Whiteley boosts her assets in a cleavage enhancing embellished black jumpsuit at the 77th annual Cannes Film Festival premiere of The Substance

Rosie  Huntington-Whiteley put on a sultry display at The Substance premiere during Cannes Film Festival on Sunday.

The model, 37, opted for a  daring jumpsuit that displayed her able bosom when she arrived at the launch of the new horror film starring Demi Moore.

Rosie's jumpsuit was emblazoned with an array of long silver tassels that went right down to the feet, and she complemented the look with a set of long hanging earrings.

The catwalk star swept her honeyed locks away from her face and secured them behind her face and  opted for a slick red lipstick to set her complexion off.

At one point , the former Victoria's Secret Angel spun around to give a glimpse of her pert behind in the jumpsuit.

Rosie then struck a sultry pose as she gazed into the camera, and also showcased her tight hair bun in a series of close-up shots.

The Substance follows Ghost actress Demi as ageing film star Elizabeth Sparkle who goes to extreme lengths to stay youthful. 

Cannes' synopsis of the film reads: 'Have you ever dreamed of a better version of yourself? You should try this new product: The Substance. It changed my life. 

'With The Substance, you can generate another version of yourself, younger, more beautiful, more perfect… Just share the time. 

'One week for one, one week for the other. A perfect balance of seven days. Easy isn’t it? If you follow the instructions, what could go wrong?”

The festival is known for its carefully selected programme of films that have gone on to Oscar glory or launched the careers of directors like Quentin Tarantino.

Cannes' top prize is the Palme d'Or, or Golden Palm, whose past winners include Taxi Driver, Apocalypse Now, Pulp Fiction, The Pianist and Parasite.
