Lady Gaga Ziplines Onto 'Good Morning America' Concert Stage

Lady Gaga kicked off "Good Morning America's" 2011 Summer Concert Series today in New York City's Central Park with an arrival that only the chart-topping singer, fashionista and cultural icon could deliver.The pop star made a grand entrance by zip-lining onto the "GMA" concert stage, a feat of gravity that even the singer's most die-hard fans did not see coming.Dancers appeared onstage amidst rising steam and flashing lights but the eyes of the thousands of concertgoers in attendance quickly moved away from the stage to a platform high above the trees of Central Park where Gaga stood wearing a harness, and also sky-high black heels.

The singer then flew in from seemingly nowhere down to the concert stage, as her fans -- or "little monsters," as Gaga calls them --stretched their hands to try to reach her while shrieking and screaming their shock and approval.

Gaga's fans, accustomed to the grandiose Gaga -- she of the meat dress and egg-like containment vessel -- began camping out in New York's Central Park as early as 3:00 a.m. Tuesday, three days before the concert.

By Friday morning, thousands of "Little Monsters" decked in Gaga garb -- from outrageous hair pieces and blonde and bubble gum pink wigs to fishnets, sky high heels, glitter and more - stretched throughout Central Park.The turnout made today's concert the biggest ever for a "GMA Summer Concert Series" event.The steam machines and unicorn statue piano on the outdoor stage gave Gaga's excited fans a glimpse of the show spectacular that was to come.

The singer herself whipped the crowd into a frenzy before the show even started when she appeared onstage for a sound check with her hair in a long blonde and black side pony tail, but that was only a preview of what was to come.

The harness and the flying entrance did not prevent Gaga from delivering on some trademark outrageous fashion.The singer flew in on the zipline wearing a white and red turban-like headpiece with a white cape.Once on stage, Gaga's dancers removed her cape to reveal the singer in red fishnet stockings with black felt pieces, a red leotard, black lace-up booties with glitter and long black nails.For her first-ever live "GMA" performance, Lady Gaga promised to deliver a high-octane range of fan favorites, both new and old. Her playlist included the singles "Born This Way," "Judas" and "Edge of Glory" from her latest album, "Born This Way," which has sold nearly 800,000 copies and been on top of the Billboard music charts since its May 23 release.

Fans also got a taste of Gaga's "Bad Romance," the 2009 single that put the singer's name, and voice, on the map.Gaga's live appearance on "GMA" caps a remarkable few months for the singer.She wrapped up her sold-out "Monster Ball" tour May 6, 2011, in Mexico City, and just weeks later was named to the Forbes' 100 Celebrity List of the world's most powerful celebs, taking the number-one spot from Oprah Winfrey.Earlier this year, Gaga became the first celebrity to reach 10 million followers on Twitter, an occasion she marked with a thank you tweet to her fans: "10MillionMonsters! I'm speechless, we did it! Its an illness how I love you…"
