According to a source who spoke to Life and Style magazine, Perry said, "She's Britney Spears all over again. It's worse. Look at those outfits. It's bad."
However, Perry took to Twitter to dismiss rumours that she compared the 17-year-old singer to the 'Toxic' hitmaker at the awards.
"Rumor control: I never said s--- bout my girl Miley. I love that ho," Perry tweeted, reports The New York Daily News.
The 25-year-old singer slammed the magazine for 'pitting girls against each other' needlessly.
"We all can co-exist," she tweeted. (ANI)
