There will be someone missing from Bradley Cooper and Lady Gaga's Oscars' performance.

It was Jackson Maine’s honeyed and husky voice, along with his vulnerability and adoration for struggling singer Ally, that made us fall in love with him in A Star Is Born.

So when The Academy announced that actors Bradley Cooper and Lady Gaga would be performing at this year’s Oscars, we were bloody excited.

Cooper. Gaga. “Shallow.” #Oscars

Any chance to see the onscreen couple perform live is met with elation from fans, who also kinda want to the pair to get together in real life.

But in a recent appearance on The Late Show with Stephen Colbert, Cooper admitted a very crucial person will be missing from the performance at the Oscars.

Jackson Maine.

“He’s gone, I’m not going to try and get him back. But I will be me singing,” Cooper told the talk show host.

“But hopefully – my hope is that – I fly back to LA and we start rehearsing – I hope to be present and enjoy it and hopefully people love the song sung that night.”

… No.

Jackson can’t be gone. Because Jackson forever has a piece of our hearts.

Cooper further shared he won’t be performing in Jackson’s signature shaggy look, but rather remain in his tuxedo from the red carpet.

Talking of his recent performance at Lady Gaga’s Las Vegas residency show to Colbert, Cooper shared that when he watched the duet back, he realised that the part of him that played Jackson, is gone.

"I watched the video back and we sang it live – I went up there and sang it – and I just look like this sort of idiot from Philadelphia who’s like singing with Lady Gaga. Luckily I was on pitch, thank God, but I was like ‘oh, Jackson’s gone’."

Shallow is nominated for Best Original Song at the 91st Academy Awards, which is the category they won at the Golden Globes in January.

Cooper, who also directed the film, is nominated for Best Actor and the film itself is nominated in the Best Picture category.

Lady Gaga, whose role in the film marked her acting debut, received a nomination for Best Actress.

Despite the absence of Jackson Maine and his beautiful husky voice, we can't wait to see Bradley Cooper and Lady Gaga perform at this year's Oscars on February 25.
