Selena Gomez exudes old Hollywood glamour in an elegant black evening dress as she joins stylish co-star Zoe Saldana at LA premiere of Emilia Perez

Selena Gomez and Zoe Saldana had the same idea as they both opted for strapless gowns on Monday night at the Los Angeles premiere of their new film Emilia Perez.

The 32-year-old Rare Beauty creator — who stepped out in a blazer mini dress last week — looked  like a billion dollars  as she modeled a snug-fitting black dress with an off-the-shoulder neckline and black opera gloves.

And the 46-year-old Avatar sensation brought a pop of color to the carpet in a gown with a billowy magenta top half.

The stars pulled their dark tresses back into low-set updos as they continued their press run for their forthcoming movie.

Gomez parted her locks in a deep side part while Saldana chose a center part for a sleek, symmetric style.

She looked typically beautiful in a full face of perfect makeup that included sultry eyeliner and shadow.

On September 6, Bloomberg reported that the multihyphenate is worth over $1.3 billion, putting her on their billionaires index for the first time. 

Meanwhile, her co-star Zoe rocked pint-tinged cosmetics that complemented her dress.

The formal look boasted a long, velvety skirt and even had pockets that the actress slipped her hands into while posing.

She was joined on the star-studded red carpet by longtime husband Marco Perego.

The two spouses, who have three young sons, shared an affectionate kiss ahead of the premiere.

Marco, who hails from Italy, wore a dark, subtly patterned trench coat over a black top, trousers, and boots.

Zoe takes on the role of Rita in the Spanish language film while Selena portrays the character Jessi Del Monte. 

The movie is set in Mexico and tells the story of a lawyer who receives 'an unexpected offer to help a feared cartel boss retire from his business and disappear forever by becoming the woman he's always dreamed of being,' according to an IMDb synopsis.

It won the Jury Prize during the 77th Cannes Film Festival in May, and the female ensemble won the Best Actress award.
