Lady Gaga goes topless in a G-string and fishnet stockings during a dance rehearsal

The 28-year-old singer left little to the imagination by going completely topless during a dance rehearsal in Austria on Sunday afternoon.

The eccentric star, who is in Vienna as part of her artRave: The ARTPOP Ball world tour, was pictured showing off her shapely derriere dressed in a neon coloured G-string and fishnet stockings.

 Keeping some modesty with white nipple guards, the pop sensation oozed heaps of sex appeal as she put in the final few touches ahead of her X-rated performance.

Earlier on in the day, Lady Gaga took to Twitter to share a picture with her beloved pooch Asia.

She captioned it: ‘Are u ready #artRaveVienna ? Were here, I can't wait to hit the stage! Asia's taking a nap she's obviously knackered!’
