Taylor Swift's Fans Banned From Tay-Gating Outside London's Wembley

Taylor Swift‘s fans will have to rethink their plans if they’re planning on clustering outside London’s Wembley Stadium for her upcoming shows — ’cause authorities aren’t taking any chances.

The venue just made it clear — if you don’t have a ticket, don’t even think about hanging around outside Wembley or the Olympic Steps during Taylor’s five-night run.

And if you’re dreaming of a Swiftie sleepover — forget it! The stadium’s in a residential zone, so setting up camp overnight could tick off locals and get you kicked out.

Entry times to the shows — which kick off Thursday — have also been bumped 15 minutes earlier — early entry’s at 3:30 PM and general admission’s at 4 PM. She’ll likely take the stage earlier than her usual 7:25 PM showtime after Paramore and RAYE perform.

It’s a major bummer for ticketless Swifties known for their Tay-gating antics. Just last month, 40,000 fans packed a Munich hillside trying to catch a glimpse of her in action.

Of course, these new security measures are in place after Taylor nixed all her Vienna shows following a thwarted terror plot … with 3 suspects arrested.

Law enforcement sources also told TMZ Taylor’s Wembley security isn’t taking any risks … getting extra private counterterrorism experts on the job to beef up protection.
