Lady Gaga ventured out in Melbourne today wearing a thick padlocked collar and revealing bra as she posed for pictures with a young fan.Black nipple pasties covered the singer’s modesty and she added giant gold earrings and black retro sunglasses to the outfit.Gaga, 26, has been touring Australia and last night debuted a new song for the audience at her Melbourne show.The song, Princess Die, has outraged fans of the late Princess Diana, who believe the lyrics refer to her tragic death in 1997.The track includes the lyrics: ‘And wish that I would go / In my rich boyfriend’s limo / Right after he proposed / With a 16-carat stone wrapped in rose gold / With the paparazzi all swarming around /So bob head your head for another dead blonde..’Princess Diana died in a car crash in the Pont de l’Alma tunnel in Paris with her boyfriend Dodi Al Fayed, who is rumoured to have proposed to her.The song is expected to be a track on Gaga’s next studio album, though it is unclear whether she will include the number on her set list for her upcoming UK performances.Gaga is no stranger to controversy, angering many with her use of religious icons and costumes in her performances, and her outlandish garb such as that famous meat dress at the 2010 MTV Video Music Awards.Incidentally, the singer brought another version of the dress out onstage at her concerts this week.Gaga revisited her meat dress by turning up on stage at one point wearing a shorter version of the frock, and presumably not with real meat this time as she energetically writhed around in front of the audience.She then stripped off the skirt part of the outfit to unveil just a meat-inspired corset and body.dailymail.co.uk
