AceShowbiz - It looks like a war is brewing between %cTaylor Swift%'s loyal fans and %cKaty Perry%'s. Before Swift's Saturday, June 27 concert in London's Hyde Park started, a number of Swifties were caught in a video booing Perry as they reacted to a commercial shown on a monitor.
In the commercial for the U.K.'s Capital FM, several musicians including Swift, Perry, %cEd Sheeran%, %cSam Smith% and more could be seen promoting the radio station. The crowd cheered when Swift appeared on the screen, and booed every time Perry showed up.
The video of Swifties booing Perry was uploaded to YouTube and, understandably, drew negative responses from Perry's fans. Many of them branded both Swift and her die-hard fans "immature."
As everyone knows, Swift hasn't been on good terms with Perry. She claimed that the 30-year-old singer tried to sabotage her tour. She then allegedly wrote "Bad Blood" off her "1989" album with Perry in mind.
