Fans crowded around a luxurious building in front of Central Park South in New York City on Friday waiting for Lady Gaga to walk out. The "Do What You Want" singer was in town to perform at New York's famous Plaza Hotel for Harper's Bazaar Fashion Week party. The event honored women in fashion, including Linda Evangelista, Brooke Shields and of course, Lady Gaga. Attendees included Donatella Versace, Liberty Ross and R&B singers Maxwell and Miguel.

When Gaga arrives, the audience knows it. The "Applause" diva made it very clear that when she sings, you also must listen. Despite the big names in the room Lady Gaga didn't hold back from snapping at the crowd, "Will you (expletive) shut up? We're playing some jazz. ... Goddamn rich people." The singer abruptly stopped singing in the middle of a song when the loud crowd continued to mingle as she was on stage.

The 28-year-old pop star sang songs from her collaborative jazz album with Tony Bennett titled "Cheek to Cheek," to be released Sept. 23. Gaga wore a black leather dress which she said her sister created for her and her hair fell short and blonde in a bob cut. "So, if you all keep it down while I sing my boyfriend a song, I'd appreciate it," she commanded to the black-tie audience once again. The "Art Pop" diva dedicated a cover of Cole Porter's "Ev'ry Time We Say Goodbye" to her family and boyfriend, "Chicago Fire" actor Taylor Kinney.

Lady Gaga is known for her opinionated remarks, outrageous fashions and big voice. After all, she is a New Yorker.

"An icon, I believe, is somebody that has a strong message behind their beauty and I think all of the women that are here tonight have that," Gaga said on the red carpet. "I'm not sure that I have it, but I am pretty happy to be on the list with all these super models, so thank you."
