Lady Antebellum and Brandy Clark hit the stage on The Academy of Country Music's Superstar Duets special, bringing their go-to karaoke jam to the big time.
"[The ACMs] were asking for a duet, and we immediately said 'Islands in the Stream,'" Lady A's Charles Kelley told ET. "Hillary [Scott] and I used to karaoke that when we first got started in Nashville."
The trio called up "Stripes" singer Brandy Clark to help them tackle the Kenny Rogers and Dolly Parton classic.
"I'm a huge fan of these guys, so it could have been the ABCs and I would have said, 'OK,'" Clark gushed. "I love 'Islands in the Stream,' too. I grew up listening to it. They were talking about it being such a huge karaoke song -- when we walk out there, honestly, and there's the teleprompter, it feels like karaoke."
But the performance would have to wait. Shortly after chatting with ET, with a hurricane rolling through Arlington, Texas, organizers were forced to delay the event by several hours. But leave it to Lady A to find the most fun way to kill time in Rangers Stadium!
