IDINA MENZEL

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.

PITBULL

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."

RICKY MARTIN

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.

DWYANE WADE

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.

TOVE LO

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.

MIRANDA LAMBERT

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."

CHARLI XCX

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.

KEITH URBAN

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.

NELLY

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.

MICK JAGGER

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.

12 of 51

LEONA LEWIS

John Shearer/Getty

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.

Continued on next slide.

STEVEN TYLER

John Shearer/Getty

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."

14 of 51

ALISON KRAUSS

John Shearer/Getty

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.

15 of 51

KELSEA BALLERINI

John Shearer/Getty

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.

Continued on next slide.

DIERKS BENTLEY

Fernando Leon/Getty

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.

17 of 51

ECHOSMITH

Duane Prokop/Getty

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.

THE BAND PERRY

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.

JUSTIN TIMBERLAKE

Christopher Polk/Getty

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.)

21 of 51

SELENA GOMEZ

Christopher Polk/TAS/Getty

"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."

Continued on next slide.

LISA KUDROW

Christopher Polk/TAS/Getty

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.

23 of 51

JOHN LEGEND

Christopher Polk/TAS/Getty

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).

24 of 51

BECK AND ST. VINCENT

Christopher Polk/TAS/Getty

"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.

Continued on next slide.

ALANIS MORISSETTE

Christopher Polk/TAS/Getty

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.

NATALIE MAINES

Christopher Polk/TAS/Getty

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."

27 of 51

ELLEN DEGENERES

Christopher Polk/TAS/Getty

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

Continued on next slide.

MATT LEBLANC, CHRIS ROCK AND SEAN O'PRY

CHRISTOPHER POLK/GETTY

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

29 of 51

MARY J. BLIGE

Christopher Polk/Getty

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."

30 of 51

UZO ADUBA

Christopher Polk/Getty

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 ...)

Continued on next slide.

31 of 51

KOBE BRYANT

Christopher Polk/Getty

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.)

JOAN BAEZ AND JULIA ROBERTS

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?

33 of 51

FIFTH HARMONY

Courtesy Taylor Swift

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.

Continued on next slide.

LITTLE MIX

Courtesy Taylor Swift

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.

35 of 51

CIARA

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.

36 of 51

FETTY WAP

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.

Continued on next slide.

NICO & VINZ

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.
