Some of y'all are overreacting.
A mentor should not make a contestant sing a song they don't like!
The point of performing is to enjoy performing and Britney should of tried to be more accepting of Beatrice's wishes and helped her find a song she liked that fit the theme instead of making her sing the song she wanted her to sing.
Some of you fans calling her a bitch for no reason.
Just because Britney is her mentor does not mean she has to aimlessly follow her wishes.
