Gaga accessorised her lace dress, which sported an almost mournful hood and cape, with black platform heels and a Coco Chanel leather handbag.
She wore her long platinum blonde hair loose under the hood, and kept much of her face hidden behind large black sunglasses.
Her slender figure however was on full display. She was reportedly on her way to a nearby bar.
Gaga is among the celebrities who have commented on the tenth anniversary of 9/11.
Speaking to MTV, Gaga was effusive in expressing her love for her home city, which featured heavily in her last album, Born This Way:
‘I mean, there’s so many stories that people don’t know,’ she said.
‘I watched the towers fall from the roof of my school, holding all my best friends. I don’t know … just, my affinity and my love and the relationship I have with New York City — it’s like the husband I never married.’
‘I wrote so many songs on this new album [Born This Way] about New York City. I mean, every song on all my albums has some relationship to New York City, but one in particular “Marry the Night,” that record is about my husband, New York.’
