Not saying she didn’t sing live we all know she did :D. But there is a pre-recoded version of BtW for whatever reason. Maybe they do that version in case of mic issues on live tv
No...they do that so she can practice the choreography without having to sing. Either way...her Superbowl "Medley" was one of the worst I have heard by anyone and I actually used to stan her...it was just disappointing.
