Ariana Grande performs medley on 'X Factor' Australia...

She may be causing a ruckus in Australia for all the wrong reasons, but Ariana Grande put her focus back into the music during her international promo tour. 

She served up an eight-minute medley of her hits including 'Problem,' 'Bang Bang' and 'Break Free' during her appearance on the Australian edition of 'The X Factor.' I don't have anything to say about the performance, but great crowd!
