I doubt anyone knows because it's a weird question. But I was at her concert on tuesday, and before she came on I think it was her playlist playing. I'm pretty sure I heard Colbie Calliat/Natasha Bedingfield/Willow Smith. If anyones been to her concert, i hope you know what I mean! Haha thanks if anyone knows :/
it depends which concert. Most of the time they have guest stars that sing before she comes on.
