Wearing custom Burberry, Irina Shayk stepped out on the carpet with her husband and Cooper's mother, Gloria Campano. The stunning black gown featured a high turtleneck and a gold chain around the waist. She finished the look with a seriously sleek bob and natural make-up.
Though the award-winning actor and Russian supermodel are notoriously private about their relationship and rarely hit the red carpet together, they joined together to celebrate Cooper's A Star Is Born success.
The highly successful film, in which Cooper plays Jackson Maine, is nominated for eight categories including Best Picture, Best Lead Actor, Best Lead Actress, Best Supporting Actor, Best Adapted Screenplay, Best Cinematography, Best Sound Mixing and Best Original Song.
Despite critical acclaim of his directorial debut for A Star Is Born, Cooper did not receive a best director nomination. "I felt embarrassed that I didn't do my part," he admitted to Oprah Winfrey during her show Oprah's SuperSoul Conversations, "I didn't do my job."
Set to be the best part of the awards ceremony tonight, Cooper and his co-star Lady Gaga will take to the stage to perform their chart-topping and Oscar-nominated song 'Shallow'.
Earlier this month, Cooper revealed to E! News that he was (understandably) nervous about his Oscars musical performance. He admitted, "I'm sure I'll be terrified."
