You've probably heard the Academy Award winning song 'Shallow' ever since A Star Is Born was released last year.
You've probably seen it performed a bunch of times, like at the Grammys, and there have been different versions done.
But people were still blown away when Lady Gaga and Bradley Cooper took to the stage at the Oscars to do a stunning rendition of the track.
They came out of their chairs in the audience and came to a simple set up of a piano and a chair. Then they belted out their notes and absolutely killed it.
Orange is the New Black star Laverne Cox wrote on social media: "Why am I trying to give a standing ovation in my apartment on my fractured foot after #LadyGaga and #BradleyCooper's performance of #Shallow at the #Oscars?
"Cause it was bonkers, beyond and insanely amazingly good. Though I applauded seated, the standing O was there in spirit."
Former America's Next Top Model presenter Tyra Banks said: "Ok, so I'm DEEPly touched by @ladygaga and Bradley Cooper's #Shallow performance."
A viewer added: "That was totally freaking magical. Simple, powerful. Felt like hearing it for the first time. And it was all one single shot."
Another said: "The whole setup of that beautiful performance was exactly the way #AStarIsBorn was shot: from the perspective of the musician. To say it was perfect would be an understatement."
A third wrote: "WE CAN FINALLY EXHALE. BRADLEY AND GAGA JUST PERFORMED #SHALLOW AT THE #OSCARS BUT WHAT DO WE HAVE TO LIVE FOR NOW????"
The song won Best Original Song on the night and Gaga was understandably blown away by the honour when she arrived on stage.
She said: "If you are watching this right now, all I have to say is that this is hard work.
"I've worked hard for a long time and it's not about winning, but what it's about is not giving up. If you have a dream, fight for it.
"If there's a discipline or a passion, it's not about how many times you get rejected or you fall down or get beaten up, it's about how many times you stand up and are brave and keep on going. Thank you."
Congratulations to Gaga and Cooper not only for their performance but also for being nominated for Best Picture, Best Actor and Best Actress.Featured Image Credit: ABC
