The pair reunited on stage to perform Nick’s recent hit ‘Jealous’ as her production rolled into town in East Rutherford, New Jersey on Saturday (11 July).

And the stars looked as if they couldn’t be happier to be sharing the stage once again as they strutted up and down the catwalk at the arena, belting out the song.
Watch their performance in the video below...
Taylor and Nick first performed together back in 2009, when she joined The Jonas Brothers on stage, and a misty-eyed Taylor tweeted a throwback picture of that occasion on Sunday.
“I feel all the feelings now. @nickjonas,” she captioned the snap.
Nick also tweeted: “Unreal feeling jumping on stage with my friend @taylorswift13 tonight at the #1989TourEastRutherford show in my hometown.
“Thank you so much @taylorswift13 for having me what an incredible memory... And all the amazing fans for the warm welcome home.”
Of course, fans will remember that Taylor has a long history with The Jonas Brothers, as she used to date middle sibling, Joe.
She recently staged a reunion with him too, as they were pictured on a double date with their new partners.

Joe is now dating one of Taylor’s best friends, Gigi Hadid, while the ‘Shake It Off’ singer is currently in a relationship with Calvin Harris.
