Taylor Swift has become unstoppable with her powerhouse guests for her "1989" tour. In her sold out concert in New Jersey over the weekend, she brought with her Nick Jonas for one song number and a few more surprises.

In a report on Billboard, Swift sang with Jonas with his hit song "Jealous" to the delight of fans. Swift also danced throughout the performance as Jonas belted some high notes.

Both singers took to social media to share the amazing night with their followers.

"Truly unforgettable night jumping on stage with @taylorswift at her sold out MetLife Stadium show," Jonas said on Instagram.

The "Bad Blood" singer also expressed her joy on Instagram over the performance.

"Last night the incredible @nickjonas sang 'Jealous' and 60,000 people sang it with us/screamed uncontrollably," she wrote.

Swift even posted a throwback on Twitter of her first performance on stage with Jonas back in 2008 as also reported by Bustle.

"I feel all the feelings now, @nickjonas," Taylor Swift posted. To which, Nick Jonas replied "Oh wow. Time flies when you're having fun ha" after their latest song performance together.

Jonas was not the only surprise though that Swift brought to the stage. According to Entertainment Tonight, her squad of famous friends Gigi Hadid, Lily Aldridge, Karlie Kloss and Martha Hunt also made an appearance.  They were joined as well by Behati Prinsloo, Candice Swanepoel and "Orange is the New Black" star Uzo Aduba.

"That was so much fun!" Aduba tweeted.

"What an awesome Saturday night. I like your Style," she added.

Swift said, meanwhile, that the audience loved Aduba's appearance on the concert.

"When @UzoAduba walked out, it provoked one of the loudest screams from the crowd I've EVER heard. I just love herrrrr," Taylor Swift said on Twitter after the concert where Nick Jonas appeared as well for a song.
