Minaj was set to perform late Sunday as a headliner at the New Jersey festival. But after DJ Peter Rosenberg disparaged “Starships” earlier in the day while introducing another performer, Wayne tweeted, “Young Money ain’t doing summer jam.”

Young Money Entertainment is the name of Wayne’s record label to which Minaj is signed.

Minaj tweeted, “I go above and beyond for my fans. But won’t ever go against Wayne’s word. What he says, goes.” She later added, “We won’t [be] disrespected.”

After tweeting, “Tonight just got interesting g,” Rosenberg defended his comments on Twitter: “last night i said nothing different than I have ever was not a personal was starships is [not good]..WHICH WE ALL KNOW IS TRUE.”

He may have a point.

In her Washington Post review of Minaj’s “Roman Reloaded,” Allison Stewart called the song a “garish,” “bubble-gum Top 40 striver that makes ‘Super Bass’ sound like a song by Tyler, the Creator. It makes matters painfully clear: Minaj’s competition is no longer the ’90s ghost of Lil’ Kim. It’s Katy Perry.”

This post has been updated to reflect Rosenberg’s exact comments.
