The "ME!" singer took over Central Park ahead of her 'Lover' album release.

Taylor Swift takes over Central Park!

The 29-year-old singer delivered an energetic and fun-filled performance during Thursday's Good Morning America, taking the New York City stage to sing her latest and greatest hits, "You Need to Calm Down" and "ME!" She also performed her 2014 hit, "Shake It Off."

Swift, who was dressed in sequin shorts, a pink sheer top and black boots, was all smiles with a bright red lip as she praised the massive crowd and thanked her fans for their support. "This is insane! Wow, thank you for doing this for us," she told GMA's Robin Roberts in an interview ahead of the performance. "This is amazing!"

In addition to over 4,500 fans descending upon Central Park, Swift's pal, Tiffany Haddish, was also in the audience, along with Bachelorette star Hannah Brown.

The pop star's performance comes hours before her highly-anticipated album, Lover, drops. On Wednesday night, Swift's father and management team hand-delivered 30 pizzas and water to the fans who had been camping out overnight to see her on GMA.

"My dad was handing out pizza overnight. As a family it blows our mind that people would wanna do that," she told Roberts. "Like, for my parents, they are like, 'That's my kid, people are waiting on the sidewalk to see her sing.' It is really astonishing to us."

Fans posted the delivery on their social media. 

This week, Swift has been keeping busy teasing her LP, her new Stella McCartney fashion collaboration, and also spending time with her pals. Earlier this week, an eyewitness told ET that Swift was out on the town with Gigi Hadid and Haim at the Bowery Hotel in NYC.

"They look like they're catching up and seem to be just having a nice time out sitting at the bar. Laughing and chatting," the eyewitness said. "At one point Gigi showed something to her friends on her phone."

Expect plenty more Swift news as she will also be doing a YouTube "Lover's Lounge (Live)," where she will feature a debut performance of a song from her new album, a fan Q&A and the release of the "Lover" music video.
