The 28-year-old 'Judas' hitmaker celebrated her birthday at the Roseland Ballroom wearing a dress that also featured some roses which were strategically placed to cover her modesty, reported Ace Showbiz.
The Mother Monster completed her outfit with a sheer red headscarf and pink platforms with red ribbons tied around her ankles. Lady Gaga held a bouquet of white rose while waving to cheering fans and posing for photographers.
"Thank you so much for spending my birthday with me. When I woke up this morning I was so happy. I couldn't wait to get here tonight. I have so many friends here ... so many fans I've grown up with for six whole years, seven whole years," Lady Gaga said.
"Thanks for making this the best birthday ever," Lady Gaga added.
