It used to be the case that fans and gossip-watchers would unpick Taylor Swift's lyrics to work out who her love interests were.
But since the release of 1989, the former country singer-songwriter's first pop album, it's Swift's female friends who keep her in the gossip columns. For the video of Bad Blood, her fourth single to be released from the album, Swift has recruited a diverse collection of her famous friends to star as Sin City-style characters - fun fact: they chose their own aliases.
With rumours swirling that Bad Blood was allegedly written about a spat between Swift and fellow pop star and former BFF Katy Perry, is this who Swift would have in her gang?
Who? Actress, best known for playing Olivia Benson in Law & Order: Special Victims Unit
Fictional Bad Blood name: Justice
Friendship status: Feline friends
One of Swift's cats is named Olivia Benson, after Hargitay's character. When Hargitay and Ellen Pompeo, who inspired the name of Swift's other cat, found themselves together in February, they took a selfie and dedicated it to the singer on Instagram, writing: "This one goes out to @TaylorSwift13 @taylorswift #CatsOutOfTheBag #NFL #NationalFelineLeague#MeowMeow #CatsMeow."
It all started when Swift named her white cat Meredith Grey, after Pompeo's Grey's Anatomy character. Weeks after Pompeo and Hargitay sent Swift a selfie, Pompeo offered a little advice after the cat-version of Grey scratched her owner, and Swift put it on Instagram. Pompeo responded in style, writing: "This is awkward because my namesake did this but as your doctor please keep that scratch clean! Yours truly, the real Dr. Grey."
Another of Swift's Victorian Secret pals, Swift appeared in an adorable Instagram video on Hunt's account in January, in which they adhere cat stickers to Swift's phone and Hunt announces it is "purrrfect". More recently, in her cover interview for Glamour, Swift named Hunt as one of her Women of Tomorrow, along with Gigi Hadid and Suki Waterhouse.
Jessica Alba has plenty of experience in being badass in new-noir cinema: she's played Nancy, a feisty barmaid-cum-vigilante in the Sin City films. However, she's not one of Swift's better known gal-pals. What Swift and Alba do have in common, however, is Jaime King. Alba is godmother to the son of her Sin City co-star, while Swift will take up the mantle for King's second child.
Who? Dancer and musician, rising star of TV as Tiana in Empire
Fictional Bad Blood name: Dilemma
Friendship status: New recruit
The rapidly ascending Empire actress popped up on Swift's Instagram, her immaculately kept certificate of new friendship, at the end of April: less that a fortnight before the news of the video collaboration. McNeill appeared as part of a rather staged photo of Swift and the girls from Californian rock band Haim, and the actress also posted a selfie of her and Swift on her own account. Swift and Seraya also appeared in a photo posted by Ellie Goulding on the same night.
It all started with cookies. Swift decided Kloss was a good person to bake them with after seeing one of Kloss's modelling shots. Vogue got wind of this and included it in the singer's first cover interview in February 2012. The inevitable Twitter conversation started between the supermodel and Swift, but they didn't meet properly until November 2013, at the Victoria's Secret Catwalk show (something Lily Aldridge, see below, was responsible for.)
They've since been on road trips and in fashion shoots together, and this Christmas Kloss's Karlie's Kookies were an essential inclusion in Swift's Swiftmas deliveries to lucky fans. Swift revealed in her Rolling Stones interview that there's a special place in her New York apartment for Kloss, complete with her favourite supplies from Whole Foods.
Swift introduced thousands of her fans to Lamar's music in November when she mimed along to the hip-hop artist's Backstreet Freestyle in an Instagram video. She went on to tell Rolling Stone she knew every single word, and dance enthusiastically along to Lamar's Grammys performance. The feeling was mutual, Lamar told the Associated Press: "You can’t put great music in different genres."
"I enjoy great music outside of my own music all the time, so I definitely can see where she’s coming from when she says that she listens to the record, and it’s a great thing for her to acknowledge that and put that good energy out into the world like that.”
If that wasn't enough, he then gave a little rendition of, and a freestyle over, Shake It Off. No haters hatin' here.
Who? Writer, director and star of HBO show Girls.

Friendship status: Lengthy and adoring
Dunham admits to writing the first season of Girls while listening to Swift's music and tweeted her appreciation of Red, Swift's fourth album, in 2012 only for the singer to reply: "You made my day with that. I'm now going to sit in my dressing room reciting my fav Girls quotes... Which is all of them. Within a year, the pair were seen hugging at the Grammy Awards. Six months later, in October 2013, Swift collaborates with Dunham's boyfriend, Bleachers and fun musician Jack Antonoff, on Sweeter Than Fiction. Out of the Woods, Swift's second single from 1989, is another Antonoff collaboration. Swift and Dunham continue to praise each other in every interview they give.
Who? Oscar-nominated child star of True Grit, model and forthcoming Pitch Perfect 2 cast member
Fictional Bad Blood name: The Trinity
Friendship status: Sisterly
Swift and Steinfeld were reportedly introduced by another Hollywood starlet, Emma Stone, and have been friends for at least three years. Swift is said to take on an "older sister" role in the relationship, and has accompanied Steinfeld to events such as her film premieres (Romeo and Juliet in 2013) as well as holidays on Rhode Island.
Aside from Madonna taking a tumble on stage, there was an awkward moment at this year's Brit Awards. When Ellie Goulding presented Swift with the gong for Best International Female, she did so saying, "the winner is... someone I'm so proud to call my friend, Taylor Swift!" A touching moment, perhaps, except when Swift thanked all of her British friends in her acceptance speech, she nearly left Goulding off the list.
By all accounts, the pair frollicked at the after party regardless. Swift initiated the friendship in 2012 after admiring Goulding's music and telling her as such when they first met - apparently the British star was "physically weirded out".
Who? American fashion model, daughter of Real Housewife of Beverley Hills Yolanda Foster

Friendship status: Slumber party buddy
Swift photobombed a photo of Hadid and her friend Kloss at a pre-Oscars party in 2014, the pair have been dominating each other's social media output ever since. Gigi has swiftly become one of the singer's downtime friends - for the kind of cute, night-in activities such as hanging Christmas decorations, singing along to Britney Spears and, most recently, talking about break-ups. Hadid and Swift were pictured hiking in Los Angeles' Franklin Canyon Park shortly after the former called off her relationship with Cody Simpson.
Pop punk and pop are surprising bedfellows, but Paramore's Hayley Williams has long been a Tay fan and friend, carrying around the Shake It Off's singer's perfume back in 2011. Their friendship peaked when they performed together on stage during Swift's Speak Now tour, and then wrote about it on her Tumblr: "Of all the friends I have who play/write music, I’ve never seen anybody do it all with as much heart and grace as Taylor does
Who? Actress, singer and dancer, former Disney kid
Fictional Bad Blood name: Cut-Throat
Friendship status: We're not entirely sure
Zendaya's inclusion is a mysterious one. By the standards of Swift's other Bad Blood crew members, she's hardly made a mark on the singer's social media output. However, this would be quite the way to kickstart a friendship, and the Disney star has already voiced her appreciation for Swift, calling her "the bomb-diggity."
Who? Victoria's Secret Angel, Sports Illustrated model
Fictional Bad Blood name: Frostbyte
Friendship status: Well cheekboned homegirls
Aldridge is perhaps one of Swift's oldest celebrity friends. The women met in Nashville, at a Kings of Leon gig - Aldridge's husband is Leon King Caleb Followill - where they learned they were neighbours and became friends. Aldridge was responsible for getting Swift on the Victoria's Secret catwalk two years running, and even though Swift has moved to New York, the pair still find time to hang out.
