The "Hello" singer shared a picture of her wearing a blonde wig and pink suit on Instagram Tuesday.
"The effortless queen of song, Dolly Parton! We love you!" she wrote. "We wish we could possess an ounce of your ability. You were the hero of our night! A hero of my life. I'll always love you x."
Clearly the costume caught Parton's attention because the "9 to 5" singer commented on the photo.
"And I will always love you!" she wrote, quoting her 1974 song that was later sung by Whitney Houston in The Bodyguard. To show how much she really loved Adele's getup, Parton added three heart emojis.
This isn't the first time the artists have fangirled over each other. In her song "Head Over High Heels," the country superstar sings, "Put on my tight dress. Hair teased on my head. I painted my lips red. And my eyes like Adele."
In fact, the "Jolene" singer said she'd love to collaborate with Adele.
"I love her! I would love to do something with her," she told Digital Spy back in August 2016. "I just love her. I love how she looks, I love how she sings, I love how she is."
We'd love a collaboration too, Dolly!
