It is no easy task to keep track of Taylor Swift's BFFs because girl keeps adding one to the list every minute. We made one over here last year, and now we have to update it because she's gained a ton of new besties in a year.
1 Camila Cabello
We're not sure when Tay and this Fifth Harmony member exactly started hanging out, but we were extremely touched when the "Style" hitmaker threw an 18th birthday bash for her when she found out that Camila had no plans that day.
2 Sam Smith
Sam and Tay-Tay first met when the latter wanted him to perform during the Red World Tour at the O2 Arena. After that, they've been spotted together and got really close when Sam attended Taylor's 25th birthday bash last December.
3 Madonna
The two music legends met during this year's Grammy Awards and performed the song "Ghost Town" together at the iHeart Radio Music Awards.
4 Beyonce, Jay Z, and Justin Timberlake
We knew they all started hanging out (and talked about ~*business*~) during Taylor's 25th birthday.

5 Haim
The pop sensation became part of the wolf pack when MTV asked musicians on who Taylor Swift should date next. Then that was followed by a Twitter friendship and then here they are now, standing beside each other.
6 Ariana Grande
Taylor and Sam's shared love for this adorable singer's music became apparent when they danced in the front row of the American Music Awards while Ari was onstage. But even before that, Ari and Tay were already friends when they met at the backstage of last year's Victoria's Secret Fashion Show.
7 Amanda Seyfried and Kate Upton
As we all know, T-Swizzle is one of the warmest persons around. So it's no surprise that she instantly made friends with her Knicks game seatmates at the Madison Garden.
8 Jack Antonoff
Jack, Lena Dunham's boyfriend, is one of Taylor's co-producers for her album 1989. Plus, her song "You Are In Love" was actually written about Jack and Lena's relationship.

9 Jaime King
The two have actually been friends for quite a while. They did the Ice Bucket Challenge together and recently, Jamie got the music sensation as her baby's ninang.
10 Martha Hunt, Gigi Hadid, and Ashley Avignone
We assume that these lovely girls might have met after being introduced to each other by Karlie Kloss or after the Victoria's Fashion Show last year where Tay-Tay performed onstage again.
11 Hayley Williams
The Paramore frontwoman has been a constant face during Taylor's major BFF moments. She'll also appear soon in her "Bad Blood" music video along with T-Swizzle's other besties.
12 Serayah McNeill and Halston Sage
Empire's Tiana and Paper Towns' Lacey were spotted in this recent squad photo posted on Tay-Tay's Instagram account.

— Zendaya (@Zendaya) April 23, 2015
Taylor cited the KC Undercover star as one of the girls in her Women of Tomorrow article for Glamour UK. Too cute, girls. We can't handle this anymore!
14 Kendrick Lamar
T-Swizzle dropped his name in interview last year, citing the rapper as the person she really wants to befriend. And of course, she gets her wish because Kendrick will appear in her "Bad Blood" music video.
15 Tavi Gevinson
This is one of our favorite friendships ever. The Rookie co-founder and EIC even interviewed her BFF for Elle recently.
