Prince William shakes it off as Taylor Swift's Eras Tour arrives in ...

Prince William has enjoyed a birthday treat boogieing the night away at the first of Taylor Swift's Eras Tour concerts in London.

Swift kicked off the London leg of her global tour on Friday night local time at Wembley Stadium.

The official account of the Prince and Princess of Wales on X shared a behind-the-scenes photo of William posing for a selfie with Swift, alongside his two oldest children, Prince George and Princess Charlotte.

"Thank you @taylorswift13 for a great evening!" the post read.

The day before, his 42nd birthday was marked with an image shared online by his wife, Princess Catherine, depicting the prince and the couple's three children, George, Charlotte and Louis.

Swift also shared a selfie with the royals, as well as her boyfriend Travis Kelce, wishing William a happy birthday.

"Happy Bday M8! London shows are off to a splendid start," she wrote.

Swift is set to play eight shows at Wembley Stadium, which has a capacity of 90,000, as part of her two-year-long world tour.

The opening night was star-studded, with Bridgerton actor Nicola Coughlan, Queer Eye's Jonathan Van Ness and model Cara Delevigne among those spotted in the crowd.

Labour leader Keir Starmer also shared a photo on social media of him and his wife in the stands.
