I've been to her concert in Amsterdam 2 weeks ago, I still find glitter in my room! But to be honest, she's cool and i like her, her performance wasn't anything like the btwb. She performed for no longer than one hour, she sung live, but there was an horrible auto-tune playing also. And she didn't even sing during every song, she just let the auto-tune sing along while she was doing i-dont-know-what. It was an amazing and memorable party, but her performance wasn't what i expected.
''Her music is actually good and her stage appareandvxcb bla bla'' maybe she could do a better job if she wants and cares, she is just lazy and wants money.
