GaGa joins trumpeter pal for impromptu performance Lady GaGa stunned partygoers in New York on Friday when she jumped on stage during her pal Brian Newman’s weekly jazz show and treated them to a special performance.

And the singer continued to live up to her reputation as a fashionista – she donned an all-black Alexander McQueen ensemble complete with John Lennon-style sunglasses.

Her Ladyship met Her Majesty last night, as Lady Gaga was politely asked “what do you do?” by Queen Elizabeth at this year’s Royal Variety Performance in Blackpool. In a surreal fashionista nod to the monarch’s ancestor and namesake – but in a less flesh-flashing manner than is her norm of late.

Lady Gaga wore a red PVC dress complete with enormous ruff and puffed sleeves, together with some bizarre jewelled red eye shadow. Maintaining whatever dignity you can when playing piano suspended 20 feet above the ground, Gaga was ultra-careful in offering the Queen the deepest curtsey her outfit would allow, both after her performance and during the traditional face-to-face meeting all performers have with Her Majesty – she was also well-versed in knowing not to speak until spoken to and to address the Queen as “Ma’am.”

However, the US singer-songwriter, aka Steffani Germanotta, was specifically banned from performing in front of the Queen her now standard ’suicide’ stage routine of stabbing herself and releasing fake blood.
