When it comes to star power, Taylor Swift doesn't just exude it, she attracts it — and the eclectic and myriad celebrities who have joined her onstage for her current concert tour prove it.

Although the Los Angeles leg of her "1989" tour wrapped Wednesday with a show that featured a rousing performance of "Smelly Cat" with Lisa Kudrow of "Friends," dozens of A-listers have made very public appearances at many of the pop star's tour stops. It's practically a traveling variety show at this point, and her fans are all about it.

In no particular order, here are 10 of the biggest and buzziest appearances from Swift's current tour to date. (Honorable mentions go to Beck and St. Vincent, who brought some serious indie cred and a shred-tacular guitar solo to Swift's traveling party; to "Orange is the New Black's" Uzo Aduba, who wowed audiences with her unexpected take on "White Horse"; to Natalie Maines for a spirited rendition of the Dixie Chicks' "Goodbye Earl"; and to Ellen DeGeneres, whose outfit was as sparkly as her smile.)

1. The World Cup-winning U.S. Women's National Soccer Team

Swift likely invited other celebrities onto the stage before her tour arrived at New Jersey's MetLife Stadium, but perhaps the first truly viral moment happened July 10, when the newly minted champs took a bow on her stage. Ever since, Swift's fans have been wondering if more stars would be waving to them from her concert catwalk — and, often, she'd deliver.

2. Hailee Steinfeld, Lily Aldridge, Gigi Hadid and Lena Dunham

Referring to them on Instagram by their character names ("The Trinity, Frostbyte, Slay-Z, and Lucky Fiori," respectively), Swift welcomed four of her "Bad Blood" music video co-stars onstage in New Jersey.

3. Nick Jonas

Swift and Nick's brother Joe broke up in 2008, but she's still Jonas-friendly these days. She and Nick had no problem rocking out to his hit "Jealous" at MetLife Stadium on July 11.

4. Julia Roberts and Joan Baez

While other tour stops had their share of celebrity appearances ranging from NFL quarterback Russell Wilson to rock band Imagine Dragons, the star power ratcheted up a few notches in Los Angeles. After Roberts and Baez joined Swift onstage during "Style," Swift took to Instagram to hail the Academy Award-winning actress and legendary folk singer as her "heroes."

5. John Legend

Swift appeared to be have a deep knowledge of every last lyric of Legend's "All of Me," and felt compelled not only to throw her hands in the air, but also to wave them like she just didn't care.

6. Lisa Kudrow

"Smelly Cat" would have been amazing if either Kudrow or Swift performed it as a solo, but the owner of a cat named Olivia Benson realized just how great it would be if they teamed up for a duet. The Internet agreed, and the moment went viral instantly. (Of course, Mariska Hargitay, who plays the original/human version of Olivia Benson on NBC's "Law & Order: SVU," walked the catwalk at one of Swift's June concerts in Philadelphia.)

7. Chris Rock

Sure, Kudrow's "Friends" cast mate Matt LeBlanc walked beside Rock, but the stand-up comedian was seen enthusiastically singing along to "Style" as they strutted down the catwalk.

8. Alanis Morissette

It shouldn't be a surprise that Morissette's break-up anthem would resonate with Swift, who's been known to pen a few songs based on failed relationships. Joining forces was an inevitability.

9. Mary J. Blige

What do you do when you've had your share of drama with Miley Cyrus, Nicki Minaj and Katy Perry? You call upon the songstress behind the triple-platinum album "No More Drama," and join her in singing "Doubt." (Of course, if you're Taylor Swift, you probably could have done that without the aforementioned drama, too.)

10. Justin Timberlake

"I have no way to deal with this," reads the caption to Swift's Instagram photo, posted just hours after she invited him to sing "Mirrors" during her tour's final L.A. performance. "Justin Timberlake is the BEST."
