Taylor Swift and Katy Perry's six year war: How the battle over back up dancers ...

Pop stars Taylor Swift and Katy Perry have officially ended their feud. Now, MailOnline has taken a look back at their fallout, from 'stealing' back-up dancers to subtle digs and diss tracks. 

The pop stars have been crossing paths for many years, and the pair even seemed to be friends for a while, gladly posing for photos together. 

But the singers were embroiled in a feud since Taylor claimed the Bon Appetit singer stole three of her backing dancers from her Red tour in 2012.  

Better times: Perry and Swift were friendly prior to a dispute over a dancer who left Swift's tour for Perry's

SEPTEMBER 2014 

TMZ reports that the feud between the performers ignited when three of Taylor's dancers quit to join Katy's Prismatic World Tour.    

Taylor releases the single Bad Blood, which was believed to be about her bitter fallout with Katy.

Added fuel to the fire, in a now infamous interview with Rolling Stone Taylor admits that the track was about a female musician - and 'straight-up enemy.'

She tells the publication: 'For years, I was never sure if we were friends or not.

'She would come up to me at awards shows and say something and walk away, and I would think, "Are we friends, or did she just give me the harshest insult of my life?"

'Then last year, the other star crossed a line. She did something so horrible, I was like, "Oh, we're just straight-up enemies." And it wasn't even about a guy!

'It had to do with business. She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me.' 

After Taylor's interview is published, Katy tweets with a possible slant in Swift's direction: 'Watch out for the Regina George in sheep's clothing,' referring to Rachel McAdams' bitchy character in Mean Girls. 

Rivalry: The unlikely feud was thrust into the spotlight in 2014 when many had speculated that Taylor's hit song Bad Blood was about Katy over unresolved personal issues between the two, as the music video was released

SEPTEMBER 2016

Katy reveals she would consider working with Taylor if her not-so-secret longtime nemesis apologies.

When a fan on Twitter asked, 'will you collab with Taylor Swift?[sic],' without missing a beat, Katy responded: 'If she says sorry, sure!' 

MAY 2017 

Katy seemingly retaliates to Taylor's Bad Blood track with single Swish Swish, which is also reportedly about their feud. 

There are plenty of references to Taylor all over the track: The most obvious one is that she calls her rival basketball team the Sheeps.

The I Kissed a Girl hitmaker makes it clear she was not going to back down from their very public spat, singing: 'Ur game is tired, you should retire.'

Lyrics include the lines, 'Don't lose no sleep/Don't need opinions/From a selfish or a sheep/Don't you come for me/No, not today/You're calculated I got your number.' 

In the track's music video, Nicki Minaj pops up (wearing what looks like a Bad Blood costume) to make it clear she is on Team Perry.   

Hitting out: Katy Perry has compounded her ongoing feud with Taylor Swift, days after calling on the singer to settle a fallout sparked by an unlikely row over three backing dancers

Speaking about her new single Swish Swish in relation to the fallout, Katy tells James Corden's Carpool Karaoke: 'That's true, there is a situation. Honestly, it's really like she started it and it's time for her to finish it.' 

Katy claims she 'tried to talk' to the blonde beauty about the feud some time ago, but claims she 'wouldn't speak' to her. 

'She wouldn't speak to me. I do the right thing anytime that it feels like a fumble. It was a full shut-down and then she writes a song about me and I'm like 'OK, cool, cool, cool. That's how you wanna deal with it?''
