I think her band trolled her and started playing Young and Beautiful instead of something else! She was "put on the spot"
She was referring to the audience when she said "you put me on the spot". Someone had shouted that she should play the song, and she said that she'd never played it live so she wasn't sure. but the crowd kept cheering and she looked at her band and then said she'd try. it sounded amazing and it was so cute when she laughed
TROLL HER AND PLAY YAYO I'm sure the crowd will SCREAM
I love the song so much! One of her best!
