Bradley Cooper gave an electric performance with his A Star is Born castmate Lady Gaga at Sunday's 91st annual Academy Awards. As fans began to ship the pair due to their insane onstage chemistry, people seemingly forgot about—or dissed—the actor's longtime girlfriend Irina Shayk.

Shayk, 33, has been with Cooper, 44, since 2015. Their relationship formed eight years after the Oscar nominee split with his ex-wife, actress Jennifer Esposito, in 2007 following a year-long marriage. Before Cooper, she dated soccer player Cristiano Ronaldo.

Shayk is a supermodel. She's appeared on the Sports Illustrated Swimsuit Issue, becoming the first Russian model to do so. She's also worked with brands like H&M and L'Oréal Paris.

Shayk and Cooper share a child together, one-year-old Lea De Seine Shayk Cooper.

Since A Star Is Born's October 2018 debut, fans have backed Cooper and Gaga as a couple despite the actor's serious relationship with Shayk. This campaign for Cooper and Gaga to get together persisted during Sunday's Oscars ceremony as the pair's onstage chemistry sparked support and rumors from fans via Twitter.

Shayk sat between Cooper and the 32-year-old "Poker Face" songstress following their intimate performance of "Shallow," a song from the duo's film A Star Is Born. The feature was directed by Cooper and follows a high-profile musician as his career begins to crumble while a newbie singer, his love interest that he introduced to the world, began to rise.

Cooper and Gaga won the Academy Award for Original Song for "Shallow."

"I love you mom and dad, Bradley....Thank you for believing in us. Thank you so much...This is hard work," Gaga said when accepting her Oscar. "I've worked hard at this for a long time...If you have a dream, fight for it."
