It was on Monday evening when Gaga made two impromptu performances at gay clubs 'Nevermind' and 'ARQ', having earlier hinted her presence through Twitter.
She posted: "Thinking of going out in Sydney tonight. How I wish we had a show. NEVERMIND, don’t listen to me. Maybe I’ll just got for a walk in the pARQ."
While Gaga's performance at Nevermind
ran as expected, it was later that evening when matters got out of hand.
Dressed as her new mermaid alter ego - Yugi - Gaga
emerged before the audience in a wheelchair.
It wasn't long before eggs were being launched from all angles - and although Gaga avoided the attack whilst maintaining an ice-white smile, one unfortunate spectator was hit square in his poker face
Based on her support for gay rights, Gaga was given honorary citizenship of Sydney just several days before.
Mayor Clover Moore said: "Lady Gaga has been a powerful force for the gay and lesbian community in Sydney and we have a rare honour for people whose achievements embrace the ideals and spirit of our city."
