Ellie Goulding parties with Taylor Swift's rival Katy Perry

British singer Ellie Goulding found herself under attack from Taylor Swift fans over the weekend (30-31May15) after posting a photo of herself partying with the Blank Space hitmaker's rumored pop rival, Katy Perry.

The Love Me Like You Do star, who previously befriended Swift, took to Instagram.com on Sunday (31May15) and shared a snap of herself surrounded by a group of friends, including mutual pal Lorde, who is in the center of the shot, wearing a red flowing dress and striking a dance move.

Perry is among the other revelers in the picture, which is captioned, "Don't really remember this but... good times."

Goulding soon deleted the snap, but not before Swift fans took note and called out the singer for hanging out with Swift's purported enemy.

While Swift has never formally named Perry as her rival, she did confirm that her latest hit Bad Blood is about a friendship gone wrong.

Swift explained the origins of the song to Rolling Stone last year (14), saying, "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) 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. And I'm surprisingly non-confrontational - you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it."

She added, "Sometimes the lines in a song are lines you wish you could text-message somebody in real life. I would just be constantly writing all these zingers - like, 'Burn. That would really get her'. And I know people are going to obsess over who it's about, because they think they have all my relationships mapped out. But there's a reason there are not any overt call outs in that song.

"I know people will make it this big girl-fight thing. But I just want people to know it's not about a guy. You don't want to shade someone you used to date and make it seem like you hate him, when that's not the case."
