First out was Nick Jonas, who, along with Taylor, performed his hit song "Jealous" to the throng of 60,000 screaming fans.

But Taylor wasn't done. Next, the 25-year-old pop megastar brought out a few of her Victoria's Secret besties, including Gigi Hadid, Lily Aldridge, Karlie Kloss and Martha Hunt -- who have all appeared with Taylor on stage during various other stops on her tour.

Model Behati Prinsloo and Candice Swanepoel, who famously topped Maxim's Hot 100 in 2014, also took the stage.

Even Emmy-winning Orange is the New Black star Uzo Aduba got in on the fun, and apparently the crowd just absolutely adored her. Taylor even tweeted that Uzo "provoked one of the loudest screams from the crowd I've EVER heard."

Taylor has been close with the Victoria's Secret beauties for some time, and even performed at the Victoria's Secret Fashion Show in December, where some said she looked even more stunning than the Angels.
