Taylor Swift fans got more than they bargained for when they arrived at the third night of her concerts at Wembley Stadium on Sunday night in London.

A group of shocked fans were joined by a musical legend, who was spotted dancing in the crowd as thousands arrived at the iconic venue.

The Liverpudlian singer was joined by his fashion designer daughter Stella McCartney and wife Nancy Shevell.

Paul was dressed in black pants with a navy blue shirt for the occasion.

Elsewhere at the star-studded concert, Phoebe Waller-Bridge proved she’s still best friends with her Fleabag co-star Andrew Scott as they party the night away.

The 38-year-old actress and director boozed alongside her 47-year-old friend in the VIP tent during the London leg of her Eras tour.

Phoebe’s appearance comes after she was revealed as one of the latest members of Taylor’s famous ‘squad’ after recently enjoying a night out with her in London.

The star-filled evening also included Kate Moss, Cara Delevingne and Lena Dunham, with the group dubbed her new London ‘girl squad’.

Taylort’s ever-expanding friendship group made sure they were in the crowd at his concerts over the three days of his tour.

Bringing star power, Sophie Turner, Ellie Goulding and Cate Blanchett lead the way as they mingle with the audience at her sold-out show.

Her London dates have so far attracted some of Britain’s biggest names, including Prince William, Prince George and Princess Charlotte.

The big names continued to flock in as celebrities were spotted among the crowds at the iconic venue, including Beatles legend Paul McCartney.

Game Of Thrones star Sophie, 28, was spotted putting on a jovial display as she wrapped her arm around friend Gracie Abrams while enjoying a drink.

Meanwhile, unlikely duo Ellie, 37, and Cate, 55, were also seen in the venue’s VIP box ahead of her performance, supported by Paramore.

Another musical legend who attended the show was Jon Bon Jovi, while Taylor’s boyfriend Travis Kelce was also present at the performance.

According to social media sleuths, Zawe Ashton, Ruby Stokes, Rebecca Adlington Christopher McQuarrie and Jade Thirlwall were also at the show.

Tickets for the show cost hundreds of pounds each and entry to the show continues to be the hottest ticket in town this weekend.

Fans can’t wait to get a glimpse of the American pop sensation before her tour hits Ireland next week. Taylor will return with five more dates at Wembley in mid-August.
