Lady Gaga wasn't actually at the 2017 American Music Awards on Sunday night, but she still managed to have a moment.

The singer performed "The Cute" via satellite from Washington, D.C., during her Joanne World Tour and posed on a mini red carpet backstage before the concert in a sexy LBD that paid tribute to designer Azzedine Alaïa -- it was his design -- one day after his tragic passing.

The stunning look showed Lady Gaga fully embracing her larger-than-life pop persona. With her hair full of dramatic, voluminous blonde curls, the "Million Reasons" hitmaker was a total knockout in the black dress and posed seductively backstage at the Capital One Arena.

The AMAs came one day after news of Alaïa's death rocked the fashion world. Gaga paid tribute to the beloved designer on Instagram with three consecutive posts, one of which featured a lengthy caption honoring the icon.

"I’ll mourn forever the loss of my friend. A true genius in not only fashion but in his heart," she wrote. "He was a king and had the highest standards of design and work ethic. He was so giving, so loving, his heart so full and pure. I️'d watch in awe as he hand made each and every piece, his fingers touching the fabric like poetry. Then he would want to feed us all, and cook with his own hands and talk for hours at the table while his dogs would run around joyfully smelling the delicious food he made us. To say he was special would be an understatement. To say he was integral, important and influential to fashion is simply not enough. There was no one who did what he did. No one knew a woman’s body like him. He should be celebrated as one of the greatest fashion designers the world has ever known. I️ love you, Azzedine."
