As the 'Bad Blood' singer Taylor Swift continues her '1989' concert tour, the famous pop star never fails to surprise her fans which have been famously referred to as the 'Swifties'. Her latest concert brought former 'Jonas Brothers' member Nick Jonas performing one of Swift's hit songs on stage.

Swift definitely wanted her fans to have the time of their lives and making the most of their purchased ticket which were reportedly sold out yet again at last Saturday's concert at the Met life Stadium. Swift apparently called up one of her longest friends in the biz, Jonas to sing 'Jealous' with her along with the thousands of audience singing along very loudly according to reports.

It was indeed a night to remember. Jonas even posted a message on Twitter reminiscing the great performance he had with Swift. "Unreal feeling jumping on stage with my friend @TaylorSwift13 tonight at the #1989TourEastRutherford show in my hometown," Jonas wrote on his Twitter adding, "Thank you so much @TaylorSwift13 for having me. What an incredible memory..."

And apparently, Jonas' friend and phenomenal performer Swift was also reminiscing her epic time on stage with Jonas. "Last night, the incredible @NickJonas sang 'Jealous' and 60,000 people sang it with us/screamed uncontrollably," Swift wrote on her Twitter.

And just as the night was thought to be almost over, Swift's girlfriends and runway models show up and make the audience even more hyped in the concert. Upon singing 'Style' on stage, Swift's known friends stepped on stage including Martha Hunt, Candice Swanepoel, Lily Aldridge, Uzo Aduba, Karlie Kloss, Behati Prinsloo and Gigi Hadid.

And Swift, being quite excited that night with all her surprises for her fans also wrote "When @UzoAduba walked out, it provoked one of the loudest screams from the crowd I've EVER heard," on Twitter adding, "I just love herrr." Then Aduba who also apparently enjoyed the stage wrote back saying, "I love youuuu! That was so much fun! What an awesome Saturday night. I like your Style ;-)."
