The five nights worth of sold out shows will kick off this Thursday and mark the end of the European leg of ‘The Eras Tour’. Each night will see over 80,000 fans in attendance.
According to organisers, for the show on Thursday, doors will now open at 3:15pm for early entry and 4pm for general admission.
For Friday’s and Saturday’s shows, early entry opens at 3:45pm and general admission opens at 4:15pm.
And finally, for Monday’s and Tuesday’s shows, doors open at 3:30pm for early entry and 4:15pm for general admission.
As well as moving up the entry times, the show is said to be starting around 15 minutes earlier than originally planned.
The changes come after the news that London's Met Police were investigating the upcoming shows following a foiled terrorist plot in Vienna last week.
Swift was forced to cancel three nights worth of shows in Austria's capital after a young man was arrested for allegedly plotting a terrorist attack in the region, focusing on the concert.
The main suspect, a 19-year-old Islamic state sympathiser, uploaded a video to social media swearing allegiance to the current Islamic state group leader and was allegedly plotting an attack at the Ernst Happel Stadium with two other young men.
A spokesperson for the London Met Police said in a statement: “The Met works closely with venue security teams and other partners to ensure there are appropriate security and policing plans in place",
“There is nothing to indicate that the matters being investigated by the Austrian authorities will have an impact on upcoming events here in London".
Wembley have announced that non-ticket holders will be forbidden from standing outside the stadium following the news in Vienna.
This is a tradition that many Swifties indulge in. Only two weeks ago 40,000 non-ticket fans in Munich sat outside the venue on a nearby hill to enjoy Swift's music and catch a few glimpses of the pop star's performance.
"To support the safe entry and exit of everyone within the stadium, no one is allowed to stand outside any entrance or on the Olympic Steps at the front of the stadium,” read an update on the venue’s website.
"Non-ticket holders will be moved on."
The five nights will feature supporting act Paramore as well as an extra supporting act each night: Sofia Isella, Raye, Suki Waterhouse, Maisie Peters, and Holly Humberstone.
