It was date night at the Oscars for Rami Malek.

The Bohemian Rhapsody star, a frontrunner to win Best Actor for his portrayal of Queen singer Freddie Mercury, and his gorgeous co-star girlfriend, Lucy Boynton, walked the red carpet on Sunday, proudly celebrating Hollywood's biggest night by posing together for the cameras. 

Malek looked dapper in a black tux from Saint Laurent by Anthony Vaccarello with a Cartier watch and cufflinks.

When ET's Nancy O'Dell asked Malek, 37, about his new romance with Boynton, who has been by his side all awards season, and said that he had already won, Boynton blushed. 

"Now you’re going to make me shy. I’m gonna look away!" Boynton adorably replied.

Malek, though, affirmed his adoration for the 25-year-old actress, who played Freddie's ex-girlfriend Mary Austin in the Oscar-nominated film. 

"I got to act against one of the most talented, powerful actors I’ve ever got to work with and she’s still on my arm," the Mr. Robot star gushed.

Malek has been collecting every piece of hardware imaginable on his journey to the Academy Awards, and he spoke about the exciting Queen medley opening the show, performed by the surviving members of the band and Adam Lambert.

"Day 1 we had [Queen's] Brian May and Roger Taylor warm up this audience, warm up us up and give us a few songs that everybody knows the words to is gonna make this Oscars a very unprecedented moment for all of us," Malek said. 

"Queen and Adam Lambert work phenomenal together," he added. "I’ve seen them five times and I gotta say this, we’re here as a small part of telling Queen’s legacy and it is the greatest honor we could have ever asked for."

During the awards ceremony, which saw Malek take home the Oscar for Best Actor in Bohemian Rhapsody, Malek and Boynton shared several sweet kisses when his name was called by presenters Gary Oldman and Allison Janney. Boynton even adorably wiped off some lipstick off Malek's face before he went onstage. 

In his acceptance speech, Malek specifically called Boynton out, calling her the "heart" of Bohemian Rhapsody, and sweetly telling her, "You have captured my heart."
