Selena Gomez cancels her 'Stars Dance' tour in Australia saying that she needs to spend some time on herself 'to be the best person (she) can be.' As John Basedow (@JohnBasedow) reports, the last time the 'Slow Down' singer was in the land down under was when she was with her now ex-boyfriend, Justin Bieber. While she may not want to relive those memories, Selena's ticket sales have reportedly been strong, but she feels it's more important for her well-being to take a break.
