this is a weird question ...... are u asking if any of those girls will have a peak as big as Gaga's???
the answer is no. if ur asking if any of them will have more successful careers overall than Gaga's career at her peak , ya i can see it for Ariana and possibly some others if they play their cards right
those are 2 separate eras and 1989 were bigger than them both individually. more #1s, more records, bigger touring, more sales, etc.
Gurl if you think, gaga's peak was only about her sales, hits and touring... You're beind stupid as ****
What Gaga had, not even Beyonce has now.. Her peak was something popstars don't usually have and it was unique
