Ariana Grande, Demi Moore and Zoe Saldana bring megawatt glamour to Oscar nominees dinner

Ariana Grande, Demi Moore and Zoe Saldana brought their megawatt glamour to the Oscar nominees dinner at the Academy Museum in Los Angeles on Tuesday.

All three women are in the running to take home gold at the awards ceremony when it takes place this Sunday night at the Dolby Theatre. 

In anticipation of her big night, Ariana, 31, who is up for best supporting actress for Wicked: Part One, was dressed to the nines for Tuesday’s evening.

She showcased her petite frame in a floor-length black gown that was gently pleated and featured a pink feathery cowl in a nod to her character in the film.

Sweeping her hair tightly back, the Dangerous Woman singer sharpened her unmistakable features with makeup for her latest night out.

Meanwhile Demi, 62, who is nominated for best actress thanks to her role in the body horror film The Substance, was luminous in white.

She opted for a sleek, streamlined trouser suit that emphasized her enviably trim figure as she beamed for the cameras at the glittering event.

Throwing her luxurious curtains of black hair fashionably over one shoulder, she accented the look with a subtle pair of earrings.

When she turned around, Demi – who won a Screen Actors Guild Award for the Substance on Tuesday – revealed her outfit had an eye-catching cutout in back.
