Nick Jonas Joins Taylor Swift Onstage & They're Proof That Anyone Can Stay Friends — VIDEOS

If you have the opportunity to attend a Taylor Swift concert, definitely go. Trust me, I'm saying this from personal experience. You will not be disappointed! I saw my first T. Swift show at MetLife Stadium last night and I'm still not over it. As expected, the 1989 World Tour was AMAZING and Swift brought out some incredible surprise guests. On Saturday, Taylor Swift was joined on stage by Nick Jonas and an assortment of her supermodel friends — Karlie Kloss, Behati Prinsloo, Gigi Hadid, Candice Swanepoel, and Lily Aldridge. Oh, and can't forget Uzo Aduba from Orange is the New Black ! Seriously, it was an unforgettable night.

Before bringing Nick Jonas onstage, Swift prefaced it by saying that her special guest was someone she's known since he was a teenager, but he is "definitely not 15 anymore." She's right! Jonas has grown up right before our eyes. Like, really grown up. The two performed his hit song "Jealous" and it was way better than the original track, in my opinion. Seeing them perform together made me think back to how these two met. It must've been in 2008, when Swift dated Nick's older brother, Joe Jonas. Awkward, right? Well, not if you're Taylor Swift, who recently has been hanging around Joe like it's NBD. She's the queen of keeping her cool and leaving the past in the past.

Check out Nick and Taylor's performance below. If you can't tell from all the screaming, the crowd was really into it.

How did we get to this point? Let's take a trip down memory lane and see the history of Nick and Tay's friendship.

Fangirling Over Taylor

Um, how amazing is this old photo? It's the JoBros freaking out over a magazine cover of Taylor Swift. There's Nick — front and center.

Hanging Out At The 2008 VMAs

Dating Nick's brother meant Taylor spent plenty of time with the "Burnin' Up" singers.

Performing Together

Back in 2008, the Jonas Brothers sang "Should've Said No" with Taylor. Ugh, the good old days.

Do you see that?! He called her "T-Swizz." That means they're very close, obviously.

How precious! The two are super supportive of one another's careers. Taylor posted this tweet in November 2014.

Back in December, Nick Jonas attended Taylor's epic birthday party with his girlfriend at the time, Olivia Culpo.

Nick referred to T. Swift and Justin Timberlake as "pretty awesome." Understatement of the century.

Nick was one of many guests, along with Joe, at Taylor Swift's star-spangled party.

And that brings us to present day, where they absolutely killed it onstage.

These two are proof that situations are only as awkward as you make them. No bad blood here at all. Long live the Taylor/Nick friendship!
