The pop sensation, whose rumoured baby bump had Sydney concertgoers' tongues wagging last week, postponed Saturday night's Melbourne concert to Sunday.
She was once again forced to announce that she also had to postpone last night's show on doctor's advice.
She also cut short her Friday night show by three songs, telling fans she was feeling "under the weather".
Her figure-hugging costumes are reportedly being altered almost weekly as her body changes shape.Celebs and Bubs
