The feud between Katy Perry and Taylor Swift was never confirmed by the artists themselves, but their fans seem to acknowledge that things are not peachy between the two internationally famous pop stars.

At the British Summertime Festival, which was held in London, Perry was heavily heckled when her image was put up on the big screen on stage.

According to Hollywood Life, may fans think that Swift’s latest track, “Bad Blood,” was inspired by the 30-year-old “Firework” singer. The release of the song seemed to have served as the official start of their so-called feud.

They were both featured in a massive jumbotron screen that was placed on the stage. The video montage played and the crowd was immediately sent into a frenzy with loud cheers. The video clip lasted for 17 seconds and it showcased the images of the artists who were part of the Top 40 list of London’s 95.8 Capital FM.

While Swift’s image received excited hoots from the huge crowd, Perry’s image was not greeted with the same courtesy. The image of the “Roar” singer was booed very loudly, and the moment was even caught on video. Since Perry appeared on the screen, not once, but twice, she got booed two times as well.

It is worth noting, though, that all of the blame must not be immediately put on Swift’s following. However, it was very clear that Swift got a lot of love from the festival crowd, but Perry was not the audience’s most loved artist.

Swift and Perry may not strike a friendship any time soon, but fans can look forward to more fun sightings between the "Blank Space" singer and new friend Emma Watson from the “Harry Potter” franchise.

Watson was spotted hanging out with Swift and the pop star’s other famous friends, models Martha Hunt and Karlie Kloss. Lauren Aquilina, an aspiring pop star who also happens to be Swift’s new friend, posted a photo of Swift and Watson goofing around together.

“Spent tonight surrounded by bad*ss girls and could not be happier about it,” Aquilina wrote on Twitter.

Swift also surprised the London crowd when her posse of amazingly beautiful, young ladies walked out on stage and walked on the ramp like it was the runway of a fashion show. What really took the cake, though, was when Jenner, walked out and became chummy with the “Style” songstress, as pointed out by another article from Hollywood Life.
