"I'm getting a lot of text messages from people wondering if I was shading Camila. No! I love her. I love her so much," Dewan said on her Instagram Story on Sunday night. "I am such a big fan of hers. I don't understand what that's about, but no. I love her."
"Guys, we were bumping and grinding so hard to "Señorita!'" Goreski added in the video.
"That's my favorite song!" Dewan declared.
Despite the drama, Cabello, 22, and Mendes, 21, had a great night. The real-life couple took home the award for Collaboration of the Year for "Señorita" -- after which Mendes shared a sweet message of support for his girlfriend.
"Thank you everyone thank you so much!! ❤️ also @camila_cabello i admire you so much you unbelievable human being thank you for being you ❤️❤️," Mendes tweeted. "We love u guys @AMAs."
