The 24-year-old Tik Tok singer said that she gave it some thought, and decided that it would be inappropriate to play concerts in Japan, given the disaster.
'My heart is with Japan right now through this disaster and these hardships,' she said in a press release.
'I genuinely don't think right now would be appropriate timing for me to perform in Japan given the content and the spirit of my show, which is all about feeling exuberant, rowdy, and wild.
'I plan to bring my party there and to that part of the world when we are all ready to dance and Get Sleazy together again. In the meantime I am going to do everything I can to help relief efforts and I encourage everyone in the world to do the same.'
