Bella Thorne cut a glamorous figure as she and her fiancé Mark Emms graced the star-studded red carpet at the annual amfAR Cinema Against AIDS gala during the 77th Cannes Film Festival on Thursday.

The actress, 26, looked incredible in a silver sheer floor-length gown which boasted a diamond embellishment from the bust to the floor.

Bella put on a busty display and flashed a glimpse of her underwear in the stylish ensemble which boasted a white bra with a sweetheart neckline.

She opted for further accessorising the look with a layer of silver bangles and a pair of simple statement earrings.

The singer added inches to her frame with a pair of ɴuᴅᴇ court stiletto heels and styled her long locks in loose waves for the evening.

Meanwhile, her fiancé Mark – who owns the New York city nightspot The Mulberry – cut a dapper figure in a navy suit.

The businessman looked suave in the dapper suit which consisted of a navy blazer with black lapels and a pair of matching tailored trousers.

Mark and Bella seemed in good spirits as they posed up a storm together on the red carpet.

Each year, the gala held in Cannes brings a slew of A-listers to the south of France to bring awareness and raise funds for the nonprofit.

Cannes is the world’s biggest film festival, first conceived in 1939 as an alternative to the then-fascist-influenced Venice Film Festival.

It has been held annually since 1946 except in 1948 and 1950, when it was cancelled due to lack of funds.

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.
