Lady Gaga Hits New York Like a Rocket

Lady Gaga sure didn't look – or sound – tired.

Following the cancellation of four previous shows due to exhaustion, the pop sensation unleashed a high-energy performance in New York Wednesday night as part of her Monster Ball Tour, and delivered the first of her four sold-out performances at Radio City Music Hall.

The singer, 23, put on quite the show for her hometown crowd, which included Sting, wife Trudie Styler, Donald Trump and, according to a source, Madonna and daughter Lourdes. She opened with "Dance in the Dark," wearing a costume featuring lightbulb-like adornments, followed by "Just Dance," with her playing a keytar and strutting onstage like a human disco ball.

"This, New York, is my first of four dates with you. So tonight I might not go all the way," Gaga teased her audience before making a sexually explicit remark that drew roars.

Concertgoers, many in their own outrageous Gaga-esque outfits, were equally tireless throughout the show. They were on their feet for the duration, dancing and singing, effectively transforming the iconic locale into a pulsating nightclub. Gaga balanced out the visual- and production-heavy show with her powerful voice in the ballad "Speechless" and a torchy revamp of "Poker Face."

Later, after putting a gay-friendly spin on "Boys Boys Boys" in a red bikini outfit, Gaga advised the crowd: "Don't you ever let anybody tell you that you can't be whatever you want. I was the little girl from New York that felt like a freak in high school."
