Star sings national anthem after touching speech at NY event...
Lady Gaga made a surprise public appearance in New York last night (June 28), making a touching speech at the city's Gay Pride rally.
And she ended with a rendition of the national anthem.
The event celebrated the US Supreme Court's decision to overturn the Defence of Marriage Act (DOMA), which had previously banned same-sex marriage.
A long-time supporter of gay rights, Lady G took to Twitter, writing: "We stand tall today. #DomaStruckDown So many fought for so long. Be proud, the prejudice are now the minority."
According to Digital Spy, she later took to the stage at the rally to give an impassioned speech, saying: "We are not a niche. We are part, a big giant part of humanity. It's time for us to be mainstream.
"My LGBT friends and fans always said to me 'I knew Lady GaGa when... well, look who the star is now.
"Now I get to say that I knew *you* when. Now I get to say I knew you when you suffered, when you felt unequal, when you felt there was nothing to look forward to. I knew you then and I knew you when, but I really know you now."
