Let's be real here, anyone willing to say no has let ATRL stan delusion take control. She doesn't have a non-#1 lead single, and her star power has only grown each era. I don't see why that's about to change.
Assuming she doesn't do something avant-garde like Rihanna, she shouldn't have a problem. If she sticks to her current formula, she'll probably debut at #1 again.
