Taylor Swift and Nicki Minaj traded words on Twitter after the rapper said she was upset she didn’t earn a nomination for video of the year at the MTV Video Music Awards (VMA).

Minaj tweeted multiple times that she didn’t understand why her rump-shaking video for Anaconda wasn’t up for the top award when MTV announced the nominees on Tuesday.

She wrote in one tweet: “If your video celebrates women with very slim bodies, you will be nominated for vid of the year.” She also tweeted, “When the ‘other’ girls drop a video that breaks records and impacts culture they get that nomination.”

Minaj did not mention specific artists in her tweets.

Swift, whose Bad Blood is nominated for video of the year, is the top VMA contender with nine nominations.

“I’ve done nothing but love & support you,” she tweeted to Minaj. “It’s unlike you to pit women against each other. Maybe one of the men took your slot.”

Nominees for video of the year include Beyonce’s 7/11, Kendrick Lamar’s Alright, Ed Sheeran’s Thinking Out Loud and Mark Ronson’s Uptown Funk.

Minaj said she never mentioned Swift in her tweets.

“Huh? U must not be reading my tweets. Didn’t say a word about u,” Minaj said to Swift. “I love u just as much. But u should speak on this.”

“If I win, please come up with me!! You’re invited to any stage I’m ever on,” Swift replied.

Anaconda, released a year ago, has 488 million views on YouTube. It earned VMA nominations for best female video and hip-hop video. Minaj is also up for best collaboration for Bang Bang with Ariana Grande and Jessie J.

Swift’s nominations for Bad Blood include best collaboration, direction, editing, visual effects, art direction and cinematography. Her other hit, Blank Space, which boasts one billion views on YouTube, is nominated for best female video and pop video.

Bad Blood, the action-packed clip that starred Lena Dunham, Selena Gomez and Lamar, has 360 million views on YouTube.

Miley Cyrus will host the 2015 VMAs, which will air live August 30 from the Microsoft Theatre in Los Angeles.
