The Squad's All Here: Keeping Up with Taylor Swift's Epic Tour Cameos

Never let it be said that she doesn't know how to go out on top! For the final stop on the North American leg of her tour in Tampa, Florida, Swift brought out Menzel to belt out the catchiest Disney song of all time – "Let It Go," of course – and since Swift is all about the treats on Halloween, she even performed in full Olaf costume. Children and parents of the world, you're welcome.

If you have a show in Miami, but don't invite Mr. 305 himself, does it really even count? That was clearly Swift's thinking when she invited the rapper out onstage to get the crowd on their feet with his hit, "Give Me Everything."

Swift made sure everyone in Miami was livin' la vida loca thanks to a special guest appearance from Martin, because everyone knows that the best way to celebrate your album's first birthday is with a stadium-wide dance party.

Even NBA superstars want to be a part of the squad – and thanks to the customized Miami Heat jersey that Wade presented Swift with onstage, it's only a matter of time before he gets invited to her house for cookies.

Because the only thing better than one pop diva is two pop divas teaming up for an epic performance, Swift recruited Tove Lo to perform her summer smash, "Talking Body," at her October tour stop in Atlanta.

Not pictured: the Lambert sat on to make this duet the ultimate display of girl power. Swift added a little extra sass to her Greensboro, North Carolina, tour stop with the help of Lambert, who brought the house down as she strutted to her hit, "Little Red Wagon."

From the "Bad Blood" music video to the 1989 tour stage: Destructa X – better known as Goulding – popped by Swift's Arlington, Texas, show for a duet of "Love Me Like You Do."

When Charli XCX joined her in Toronto, Swift dressed for the occasion – in a brand new, coordinating tour outfit. After all, nothing says "squad" like themed dressing.

We're not sure if we're more jealous that the audience in Toronto got to witness Swift and Urban's killer performance in person, or that they got to come face to face with two of the greatest bobs in the business.

Never let it be said that Swift doesn't know how to throw a party! For the Haim girls' last night opening on the 1989 tour, Swift brought out Nelly for a stadium-wide dance party to "Hot in Herre." And they even had matching outfits and choreography, because that's just how this squad rolls.

Sure, it's insanely cool that Swift got to perform with a rock 'n' roll legend, but it's even cooler to have it confirmed for us that she does, in fact, have moves like Jagger.

Nobody can resist a dramatic power ballad about love. That's especially true of Swift, who, just like us, made sure to add plenty of air-grabs and hands-on-hearts when she belted out "Bleeding Love" alongside Lewis in Nashville.

It's probably safe to say that a record number of tears were shed in Nashville when Swift and the Aerosmith rocker teamed up for a rendition of "I Don't Want to Miss a Thing."

Those heart eyes Swift is directing at Krauss? That's pretty much the exact same expression we've been wearing since Swift posted this picture following her first 1989 tour stop in Nashville.

As if we didn't have enough reasons to be jealous of Ballerini – those perfect beachy waves, for starters – the rising country star has officially earned a highly coveted position in Swift's squad: "BE MY LITTLE SISTER PLS," Swift captioned an Instagram of the pair onstage together in Nashville.

Is there anything in the world more fun than watching Swift get back in touch with her country roots on her 1989 tour? This shot of her having the time of her life onstage with Bentley in Kansas City suggests not.

Who are the real winners of The 1989 World Tour (besides, well, all of us)? That would be Echosmith, who have gotten to join Swift onstage not once, but twice.

Another tour stop, another epic stadium sing-along, this time courtesy of the The Band Perry, who joined Swift in Indianapolis to sing their hit "If I Die Young."

Sure, getting to see Swift sing one of the biggest songs of the summer alongside Khalifa is pretty amazing. But knowing that you're being serenaded with the same song that Swift regularly sings to her cats? That's priceless. Consider us officially jealous, Houston.

Okay, Taylor, you win; we lose. We have no (we repeat: no) chill left after Swift brought out Timberlake to perform "Mirrors" at her fifth and final August tour stop in Los Angeles. "Anyone who knows me knows this is my favorite artist," she told the crowd before he took the stage. (Same.)

"Hey, want to hang out tonight? I have this show thing – you should come!"
– the imagined conversation between Swift and her best friend before hitting the stage together in Los Angeles to perform Gomez's "Good for You."

Think of the 1989 World Tour stage as a really, really big coffee shop, Phoebe! The Friends alum brought back "Smelly Cat" – a song she says she hasn't performed since the series ended – and the only thing missing from their L.A. duet was Swift's own cat squad.

How many tears have we shed listening to "All of Me" on repeat? We'll never tell – and, no, we're not crying thinking about Swift's L.A. duet with Legend (that's just our ... allergies).

"St. Vincent casually slaying that guitar solo while pyro goes off in the background. Beck and I having a dance party. I don't know how to process any of the events of tonight." And so sums up our feelings on Swift's guests at that same L.A. show.

Before there were "We Are Never Ever Getting Back Together," "Back to December" and "I Knew You Were Trouble" – you know, to name a few – there was "You Oughta Know," which Swift called "probably inarguably the greatest breakup song of all time" before her epic duet marking her third night playing the Staples Center in Los Angeles.

Pass us those tissues: We're getting a little emotional thinking about Swift's nod to her country roots, which she threw back to in L.A. with her duet to Dixie Chicks jam "Goodbye Earl."

Who wore it better? Something tells us DeGeneres might have won this battle of the glitter during her strut on stage, set to "Style."

If you were thinking Swift's tour needed a cute guy squad, well, dreams really do come true on the 1989 World Tour runway.

What's better than one duet, you ask? Blige surprised L.A. fans with not one, but two performances with Swift to "Doubt" and "Family Affair."

In her return to the 1989 World Tour stage (this time in L.A.), the multi-talented Orange Is the New Black star proved, just like us, she knows all the words to Swift's "White Horse" and can sing them perfectly. (Okay, so maybe we don't have that last part in common with Aduba ...)

The NBA superstar not only came out to greet the crowd at her first L.A. show, but he also revealed a special banner dedicated to Swift that will hang alongside Lakers banners: "Taylor Swift Most Sold Out Performances." (We're not crying; you're crying.)

It's not hard to see why Swift would consider these two her "heroes:" After all, Baez is one of the most iconic singer-songwriters of all time, and Roberts is one of America's reigning sweethearts. Remind you of anyone in particular?

Last-minute choreography rehearsals, extra soundchecks, finding an extra tour costume for Swift – sure, it was a lot of work, but we're sure the ladies of Fifth Harmony would say that every second was more than worth it for the experience of getting an invite to the 1989 stage.

There's no doubt that a Little Mix/Swift collaboration is pretty much pop perfection. What we're really wondering is just how unstoppable these ladies will become now that Swift is officially part of their girl-power coven.

Are #DancePartyGoals a thing? Because we're pretty sure Swift and Ciara (who stopped by in Seattle with boyfriend Russell Wilson) are setting the bar incredibly high for the rest of us.

Well, we officially picked out our dream song when Swift inevitably invites us out for karaoke night: "Trap Queen," which she jammed to with Fetty Wap himself at her Seattle tour stop.

When Swift throws a summer party, she goes all out – like, say, calling up Nico amp Vinz, whose song "Am I Wrong" has been stuck in everyone's head since the weather started warming up.

She's got that red lip classic thing that we like, they've got a song called "Classic" – really, it was only a matter of time before Swift and MKTO got together for a sing-along.

Sure, Swift described the experience of singing one of the biggest songs of the summer, "Shut Up and Dance," as a "60,000 person dance party," but isn't that how we'd sum up every single one of her 1989 tour stops?

We'd probably say something about how awesome it was to see Taylor Swift get back to her country roots with their duet to "Take Your Time" in Chicago, but we're a little too busy swooning over Hunt at the moment.

Not only did Serayah – a.k.a. Dilemma a.k.a. Empire's Tiana – get to walk the runway in Chicago, but she also got to live out our dream of singing one of Swift's songs with the singer herself – something we have been rehearsing every day in the mirror since, like, forever.

We might not be members of Swift's squad, but at least we got to be included in her Washington, D.C. reunion with Lorde.

When you're watching Swift perform, it's hard to remember that she's just a regular human being like the rest of us, but the fact she's also had Derulo's "Want to Want Me" stuck in her head all summer (before inviting him onstage in D.C.) helps a little.

Forget the catwalk filled with Swift's besties and "Bad Blood" costars: We just finished binging Orange is the New Black, which made this East Rutherford, New Jersey, show all the more exciting.

No offense to The Trinity, Frostbyte and Slay-Z, but our favorite part of Swift's "Bad Blood" re-enactment in New Jersey was watching Lucky Fiori (Dunham) get to ham it up for her moment in the spotlight.

There's patriotism, and then there's inviting the entire World Cup-winning U.S. Women's National Team for a celebratory "U.S.A" chant.

We think Swift herself summed this one up best: "I feel all of the feelings now." Same.

We're just going to assume that Swift can predict the future, so consider Williams's appearance at her London concert an early celebration for the tennis superstar's Wimbledon victory.

On the surface, Hargitay's appearance at Swift's show in Philadelphia was awesome because it allowed Swift to have a mini-"Bad Blood" reunion onstage, but really, it was all about getting to witness the life-changing meeting between Olivia Benson the cat and her namesake.

Honestly, we're just comforted by the fact that Swift still regularly rocks out to "Radioactive" as well.

Another concert, another introduction to the newest member of Swift's squad. Pejic, who walked the runway with Lily Donaldson in Chicago, is further proof that the 1989 stage is the hottest runway in, well, the world.
