Iggy Azalea covered this week's issue of Billboard as its Hot 100 No. 1 artist, and called out Lorde's Nirvana tribute at the Rock and Roll Hall of Fame Induction Ceremony.
"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 told the magazine. "Lorde is not Kurt Cobain's peer. No matter if she killed the performance or not, I just don't think it's appropriate."
During the April 10 performance in Brooklyn, Kim Gordon, Joan Jett, Annie Clark and Lorde each sang a Nirvana song with Pat Smear and previous Nirvana members Dave Grohl and Krist Novoselic. Lorde finished out the set with "All Apologies."
Earlier this year, Lorde blasted Complex for throwing Azalea "under the bus" with a harsh review after profiling her. At the time, the "Fancy" singer responded with "#GoGirl." Lorde has yet to comment on Azalea's Billboard quotes.
CORRECTION: This post previously stated that Dave Grohl was an original member of Nirvana. Grohl did not join the band until after their debut album, "Bleach," which was recorded with Chad Channing and Dale Crover on drums.
