like every non-Avril and Clarkson stan comfirmed this fact! Avril has biggest following on social media, bigger streaming, bigger album and singles sales! Clarkson is just local popstar with Breakaway and Stronger being her only eras where she was relevant outside of the US for a little bit.
Plenty of commenters who are stans of neither have said Kelly. But, keep trying. You'll always be the one who said "Breakaway" (an Avril track) is Kelly's only international hit to me.
