The singer slipped into two bell-shaped sleeve dresses

She's already shocked fans and onlookers with a few different outfits, including a dramatic floor-length beaded gown, that appeared to reveal Spanx underneath, plus a pair of her over-the-top platform boots.
Gaga seems to be in very good spirits while Down Under, and this may be due to the fact that her beau Taylor Kinney has joined her on tour.
The couple were spotted looking rather loved-up on her hotel balcony and later that day she tweeted: 'And I had a lovely time in Sydney today. I went to Luna Park, rode the mouse-coaster & had a nice lunch by the water. Very romantic city!'
Gaga also tweeted a photo of herself laying in her hotel bed earlier in the week, looking rather tired, and wrote: 'Having the best time. Night night lil cuties. I can hear you singing from my balcony.'
