It certainly fits with her BTB style, and it's kind of influenced by her as some critics have stated. The pre-chorus isn't that high (it's high but not impossible). Actually, it's Ariana's chipmunk-ish tone that leads you all to think it's terribly high. She belts from F# to G#, which are notes Xtina has recorded before and even hit live but she couldn't hit them nowadays live, in studio she did with Your Body.
Ariana struggled singing that part live too. Oh, and to the Beyoncé stans what on earth makes you think Beyoncé would do it with ease? Anything above F5 is a challenge for her, even with all her technique and ****. She's an amazing singer but she is not a high belter by any means. Get educated before throwing shade.
