anyway, Katy is long past the indestructible stage. Roar and PRISM were kinda guaranteed to go #1 no matter what after Teenage Dream but now Katy really needs to put in some effort to get that success. It's totally achievable, but it's not 100% guaranteed.
If her next lead single isn't the tea it could pull an Applause/4 5 Seconds and get stuck at #4 or even worse. She WILL NOT get another Part of Me lead single where it goes #1 even without it being a hit in the real sense ever again. Her album is a lot more likely to go #1 but with all of these leaks lately anything is possible. She just needs to release it at the right time where the competition isn't something to worry about.
