The star also sported blonde tresses – a look which saw her accused of ‘trying to be white’ earlier this week –  were styled into an elegant half up, half down look.

She oozed confidence posing for shutterbugs with her hands at her sides and her curvy legs crossed.

Blue, who joined Beyonce on her Renaissance tour as a dancer, wore a one-shouldered black gown with a structured shoulders and futuristic shades.

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

A source close to Taylor told DailyMail.com said: ‘Taylor and Beyonce have been chatting a lot since Beyonce surprised her at her Eras film premiere. They would seem like unlikely friends but the two of them truly get each other. In a world of copycats and wannabes both are at the top of their game.

‘Beyonce cemented such a special place in Taylor’s heart in 2009 when she shut Kanye down. They both know now that karma took care of Kanye exactly as they believed it would.

‘At the time, Taylor was not the powerhouse she is today. It was just so showing of who Beyonce really is and ever since that moment the two of them have celebrated each other’s successes. Their music is very different. Their fans are very different, and their lives are so different.

‘But one thing that they can both relate on is that they are a master of their craft. There is nothing that Taylor would not do for Beyonce, and she will go to bat form this woman until the day she dies.’

A source told The Sun that it was ‘the most tightly guarded premiere this year’ as it brought Swifties and the Beyhive together.

‘Because of the stars’ fan bases, crowd control measures were put in place to make sure everyone was safe,’ they dished.

This comes as it was revealed Taylor and Travis will move in together for good if their ‘practice run’ at his $6 million Kansas City mansion goes well, according to insiders, who claim the loved up ‘soulmates’ have discussed a family.

A moving truck was spotted outside the NFL star’s new pad on Tuesday – just one day after Taylor, 33, wrapped the South American leg of her Eras tour with a sold out concert in Brazil – with furniture and other items pictured being carried inside.

The couple, who started dating in September, are said to be ‘obsessed’ with each other, with the pair flying to and from his games and her concerts to spend time together.

‘While Taylor is not officially moving in with Travis, her friends and family believe she isn’t exactly moving out either,’ a source close to the Blank Space singer told DailyMail.com exclusively.

‘I’m so glad I’ll never know what my life would’ve been like without @beyonce’s influence,’ she captioned the clip. ‘The way she’s taught me and every artist out here to break rules and defy industry norms.

‘Her generosity of spirit. Her resilience and versatility. She’s been a guiding light throughout my career and the fact that she showed up tonight was like an actual fairytale.’

Beyonce’s London bash comes after the Los Angeles premiere of the Renaissance film, which was held at the Samuel Goldwyn Theater.

It attracted a star-studded crowd including her Destiny’s Child bandmates Kelly Rowland and Michelle Williams.

And the film’s latest trailer gave a peek at Beyonce reuniting with the former members on stage for an epic performance.

The LA premiere was a private affair with guests receiving a ‘save the date’ invite that only included the time and a dress code which requested ‘cosy opulence’.

According to Variety, the location of the theatre was only revealed to Beyonce’s guests just 24 hours before the screening took place.

The publication reported that guests were advised to ‘take a ride share to an address in Beverly Hills, where they were then directed to the location of the screening’.

An announcer told guests no photos or recordings were permitted in the theater as Beyonce entered when the lights were dimmed.

For her big night, the multi-Grammy Award-winner turned heads in a rear-length platinum wig and a stunning silver Versace gown.

The star’s ethereal look sparked rumors that she ‘lightened’ her complexion — something her mother Tina Lawson shutdown in a fiery Instagram rant this week.

She furiously struck out at online critics in a post shared Tuesday, writing that she was over people ‘attacking’ her daughter.

According to the official synopsis for the film, the project ‘accentuates the journey of RENAISSANCE WORLD TOUR, from its inception, to the opening in Stockholm, Sweden, to the finale in Kansas City, Missouri

Tina accused her daughter’s critics of perpetuating ‘Jealousy and racism, 𝑠e𝑥ism, double standards,’ instead of ‘celebrating a sister or just ignoring if you don’t like her.’

Beyonce’s premiere guests included mom Tina as well as Lizzo, Janelle Monáe and Lori Harvey.
