UPDATE: On Thursday, Nicki Minaj responded to Katy Perry with an emoji.

EARLIER:After Nicki Minaj tweeted about her lack of VMA nominations on Tuesday (“If your video celebrates women with very slim bodies, you will be nominated for vid of the year”), Taylor Swift responded, saying “It’s unlike you to pit women against each other.”

The two debated on Twitter, drawing a huge audience and inciting a conversation about feminism and pop stardom. On Wednesday, Katy Perry weighed in on their discussion.

Perry also gave props to Rihanna, whose “Bitch Better Have My Money” video was not nominated for any VMAs despite coming out within the nominations window.

Swift received a total of nine VMA nominations for her “Bad Blood” and “Blank Space” videos, while Minaj only earned three for “Anaconda.” (Notably, her collaboration with Beyonce, “Feeling Myself,” was shut out completely.) Following Tuesday’s discussion, Minaj posted a note to Instagram saying her tweets were not against any single female artist but “a system that doesn’t credit black women for their contributions to pop culture as freely/quickly as they reward others.”

“We are huge trendsetters, not second class citizens that get thrown crumbs. This isn’t anger. This is #information,” Minaj wrote. “It’s all love to MTV. Kisses to my fans and thank you for my three nominations.”
