Pop star Taylor Swift stopped by Metlife Stadium in New Jersey for back-to-back concerts Friday and Saturday night in which the first performance saw surprise appearances from the celebrated U.S. Women's National Soccer Team. Saturday night brought its own lineup of all-star celebrities, this time including everyone's favorite Litchfield inmate and one of three Jonas brothers.

The 25-year-old singer brought out Uzo Abuda, known as "Crazy Eyes" from the Netflix hit series Orange is the New Black. Abuda participated in the concert runway during Swift's "Style" along with models and Swift's gang of galpals, Candice Swanepoel, Lily Aldridge, Karlie Kloss, Behati Prinsloo, Martha Hunt and Gigi Hadid, notes Entertainment Weekly.

"I ADORE THESE GIRLS," Swift captioned a group shot from the gig on Instagram.

Friday night's show assembled Kloss, Hadid and Aldridge as well as Swift's "Bad Blood" video stars Hailee Steinfeld and Lena Dunham. Also gracing the East Rutherford stage for Saturday's performance was Nick Jonas, tackling a duet of his popular track "Jealous." Diehard Swift fans remember the days she and Nick's older brother Joe Jonas shared a fling. The singer songwriter addressed the fans among a crowd of 60,000 people and explained that she's known Jonas since the young age of 15, adding "he's definitely not 15 anymore" notes People.

Swift's next stop for the "1989" tour will be in Washington, but that doesn't slow down the singer from helping those in need. The "Blank Space" singer is known for extending a helping hand to those in need or simply giving back to fans who support her—she's recently paid off one lucky fan's student loans and donated a generous $50,000 to an 11-year-old fan battling cancer.
