Lady Gaga doesn't spare audience blushes as she strips off for costume change... before slurping beer on stage

 She isn't exactly shy when it comes to showing off her body.
But Lady Gaga went one step further on Tuesday when she performed a costume change onstage in Milan, Italy, appearing nearly naked as she removed her bra and hot pants while swinging her microphone in the air.
Wearing a cap over her dark hair, she showed off her back tattoos while an assistant prepared a multicoloured wig and another dresser helped her into a pair of neon yellow panties.

She appeared to be swapping a revealing black leather ensemble for that of a neon and perspex outfit which consisted of multi-coloured straps running down her chest and back.
'#artRaveMilan let's get this party started with some killer hair and make-up,' she tweeted before the big show.

The eccentric 28-year-old singer - whose real name is Stefani Germanotta - is in the city for the latest leg of her ArtRave: The Artpop Ball tour.
Meanwhile, the star recently discussed her relationship with 33-year-old boyfriend Taylor Kinney, explaining how much she treasures his continued support of her career.
She told the Times 2: ‘What has made me so happy with Taylor is that he fiercely loves me from the inside out.’

The Bad Romance crooner added: ‘He’s very supportive of everything that I do. He’s the first man that I have dated that, when I sing onstage, he cries. That means more to me than anything.’
While the world is fascinated by her outlandish attire and stage performances, Gaga admitted that her boyfriend is able to see past it all.
She told the publication: ‘And he is completely blind to the way that I dress, my creative process as it is – he knows me as the Italian-American girl my mother and father gave birth to.’
