Taylor Swift has already boarded her private jet to depart London after a whirlwind 12-hour visit to attend Beyonce’s Renaissance premiere on Thursday.

The singer, 33, dazzled as she walked the red carpet in a glittering sequined Balmain gown – while Beyonce, 42, flashed her underwear in a very risque gown.

Taylor had been in Kansas City with boyfriend Travis Kelce and was clearly eager to see him as she boarded her flight while the premiere was still in full swing.

Photographs taken at London’s Stansted Airport show Taylor being escorted to the plane under an umbrella and surrounded by a three-car security convoy. She is expected to return to the United States.

Taylor wore her blonde hair in soft waves and sported her signature feline flicks of liner and red lipstick earlier in the evening, thanks to her epic, thigh-high slit.

She accessorized with Anito Ko glittering jewelry and Giuseppe Zanotti black platform heels.

The star was there to support her friend Beyonce, who had attended her own The Eras movie premiere in Los Angeles earlier this year – and had flown into the UK capital on her private jet.

Beyonce made her grand entrance wearing a fitted black blazer dress and little else, accompanied by her fashionable daughter Blue Ivy, 11.

Beyonce’s gown hugged her curves and had a low neckline.

The actress also wore her blonde hair in an elegant half-up, half-down style, which prompted her to be accused of ‘trying to be white’ earlier this week.

She exuded confidence as she posed for photographers with her hands at her sides and her curvy legs crossed.

Blue, who was a dancer on Beyonce’s Renaissance tour, wore a one-shouldered black gown with structured shoulders and futuristic shades.

At the star-studded premiere, Taylor and Beyonce were joined by BFF Blake Lively, Destiny’s Child bandmate Michelle Williams, and Will.i.am.

‘Taylor and Beyonce have been chatting a lot since Beyonce surprised her at her Eras film premiere,’ a source close to Taylor told DailyMail.com. They may appear to be unlikely friends, but they truly understand each other. Both are at the top of their game in a world of imitators and wannabes.

‘When she shut down Kanye West in 2009, Beyonce cemented such a special place in Taylor’s heart. They both know that karma took care of Kanye exactly as they predicted.

Taylor was not the powerhouse she is today at the time. It was just so Beyonce, and ever since that moment, the two of them have celebrated each other’s success. Their music is quite distinct. Their fans are vastly different, as are their lives.
