"This is really embarrassing for me," the 19-year-old began with brother Finneas by her side after "Everything I Wanted" won the award.
"Megan, I was gonna write a speech about how you deserve this, but then I was like there’s no way they’re going to chose me. I was like, 'It’s hers!' You deserve this," the "Therefore I Am" singer said.
"You had a year that I think is un-toppable. You are a queen. I want to cry thinking about how much I love you. You are so beautiful. You are so talented. You deserve everything in the world. I think about you constantly, I root for you always. You deserve it, honestly."
"Genuinely, this goes to her. Can we just cheer for Megan Thee Stallion, please?"
After her somewhat awkward dedication, Eilish went on to finally accept the award herself. "Thank you to the Academy. Thank you to Ringo [Starr]," Eilish concluded. "Thank you to my brother Finneas. Thanks for doing this. Thank you. I love you."
Though she may not have actually taken home Record of the Year, Stallion had a very successful night. She was crowned Best New Artist and was awarded Best Rap Song and Best Rap Performance. She also made jaws drop when she took the stage alongside Cardi B for a steamy and salacious performance of "WAP."
In the Record of the Year category, Stallion and Eilish were up against Doja Cat for "Say So," Dua Lipa for "Don’t Start Now," Post Malone for "Circles," Roddy Ricch for "ROCKSTAR," Black Pumas’ "Colors" and Beyoncé for "Black Parade."
Last year, Eilish also felt undeserving of her Big Four awards and felt that Ariana Grande deserved Album of the Year instead.
