Taylor Swift is on a roll when it comes to inviting special guests onstage during performances for her massive 1989 Tour. Just 24 hours after surprising the crowd by bringing famous friends like model-mogul Heidi Klum, actress-director Lena Dunham, R&B singer The Weeknd, model Gigi Hadid, and the entire champion U.S. women's soccer team onstage during her set, the "Bad Blood" singer invited yet another special friend to perform with her during her second concert at N.J.'s MetLife Stadium on July 11—Nick Jonas.

Swiftie invited the former Disney star and Jonas Brothers member on stage to perform a duet rendition of Jonas' mega-hit "Jealous," the Top 10 single off his self-titled sophomore album, and the sold-out crowd of 60,000 went crazy for it!

Wearing a white bustier with sparkly trim, matching high-waisted shorts, and thigh-high black boots, Taylor strutted alongside Nick as the two marched down the stage towards the crowd, the two often taking turns singing as well as harmonizing with one another. Occasionally, Taylor busted out with some sexy, hip-swiveling dance moves for her singing partner. No need to make Nick jealous, Tay!

Afterwards, the two shared a warm, friendly hug, waved to the crowd, and walked back towards the front of the stage with one another arm-in-arm before Jonas departed.

Nick and Taylor have been friends for quite some time now—he even attended her 25th birthday bash last year—so it's fun to see the two sharing the stage. And who knows, if Selena Gomez gets her wish and "Bad Blood" gets a sequel video, maybe Nick can join the squad permanently!
