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, surrounded by rising steam and flashing lights -- but the eyes of thousands of concertgoers quickly moved from the stage to a platform high above the trees of Central Park, where Gaga stood wearing a harness, bright red hair and sky-high black heels.

She flew from the trees down to the concert stage, as her fans -- or "little monsters," as Gaga calls them --stretched out their hands to reach her, to join her dancers on stage and finish out the song that heralded her "GMA" concert arrival, "Bad Romance," the 2009 single that also put the singer's name, and voice, on the map.

"I love my fans so much. Thank you for coming out today," Gaga yelled to the still-screaming crowd.

The singer had reached out to her fans to reveal her excitement for the "GMA" concert early Friday morning on Twitter, writing, "Ok so I didn't sleep. Too excited to see monsters. Let's hit it Good Morning America. We were #BornThisGma."

"You like to make an entrance, don't you!!" said "GMA" anchor Robin Roberts to Gaga as the singer sat down with Roberts and fellow "GMA" anchor George Stephanopolous after the show's opener.

"I live halfway between reality and theatrics at all times," Gaga explained.

"And I was born this way," Gaga said, a reference to her just-released album "Born This Way," that has sold nearly 800,000 copies and topped the Billboard music charts since its May 23 release.

Gaga's live appearance on "GMA" caps a remarkable few months for the American singer.

Earlier this year, Gaga became the first celebrity to reach 10 million followers on Twitter, an occasion she marked with another tweet to her fans, this one a thank you: "10MillionMonsters! I'm speechless, we did it! Its an illness how I love you…."

She wrapped up her sold-out "Monster Ball" tour May 6, 2011, in Mexico City, and just days later was named to the Forbes' 100 Celebrity List of the world's most powerful celebs, taking the number-one spot from Oprah Winfrey.

Combined with the three trophies Gaga took home at this year's Grammy awards, it's been quite a year for a singer who first rose to prominence just three years ago with the 2008 release of her debut studio album, "The Fame," a critical and commercial success led by pop singles like "Just Dance" and "Poker Face."
