In this week's Billboard cover story, reigning Hot 100 No. 1 artist Iggy Azalea had some critical words for another young superstar who's no stranger to controversy.
The target was Lorde and the topic was her recent collaborative performance with the surviving members of Nirvana at the Rock and Roll Hall of Fame Induction Ceremony on April 10 in Brooklyn.
More on Iggy Azalea:
"Nothing against her, but I think when you're doing a tribute to someone that's dead, generally it should be the person's peer," Azalea commented. "Lorde is not Kurt Cobain's peer. No matter if she killed the performance or not, I just don't think it's appropriate."
Given her recent history of diving into spirited debates about the music industry, a rebuttal from Lorde on Azalea's comments would not be surprising.
Azalea's "Fancy" (featuring Charli XCX) sits at No. 1 on the Hot 100 for the second straight week. Lorde's debut single, "Royals" topped the Hot 100 for nine weeks in the fourth quarter of 2013.
The Australian-born rapper doesn't mention Joan Jett, St. Vincent or Kim Gordon, all of whom also filled in for Kurt Cobain with drummer Dave Grohl and bassist Krist Novoselic at the ceremony.
