Taylor Swift dazzled everyone on the red carpet at Beyonce’s Renaissance launch in London on Thursday.

While Rihanna 33, who has been holed up in Kansas City with boyfriend Travis Kelce, opted for old school Hollywood elegance in a shimmering sequined Balmain gown, Beyonce, 42, showed off her underwear in a pretty suggestive costume.

Particularly when the singer wore her blonde hair in loose waves and applied red lipstick and liner in her signature feline flicks, Taylor’s dramatic, thigh-high cut flaunted a lot of leg.

Her accessories were glittering jewelry from Anito Ko and black platform heels by Giuseppe Zanotti.

At the premiere, the actress is there to cheer on her buddy Beyonce. The Crazy in Love singer visited the UK capital earlier this year on her own aircraft and went to the Los Angeles premiere of her own movie, The Eras.

Arriving with her gorgeous daughter Blue Ivy, 11, Beyoncé looked amazing in a form-fitting black blazer dress and simple accessories.

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

The actress also wore blonde hair, which earlier this week sparked accusations that she was “trying to be white.” Her hair was fashioned in a sophisticated half-up, half-down fashion.

With her hands by her sides and her voluptuous legs crossed, she exuded confidence as she posed for photographers.

Blue, a dancer who went on Beyonce’s Renaissance tour, wore a black gown that had one shoulder and was structured, along with futuristic-looking shades.

Beyonce’s bandmate Michelle Williams from Destiny’s Child, BFF Blake Lively, and Will.i.am attended the star-studded premiere with Taylor and Beyonce.

“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. Despite their seeming differences, the two of them are genuinely compatible. In an industry full of imitators and pretenders, both are the best at what they do.

When Beyoncé closed down Kanye in 2009, Taylor’s heart was forever changed. Now that they both know, karma treated Kanye just as they had hoped.

Taylor wasn’t the force she is now at the time. Ever since, the two have praised each other’s accomplishments, as it was a true reflection of who Beyonce is. Their sound is radically dissimilar. Their lives are very different, and so are their fans.

The singer and her boyfriend, Travis Kelce, have taken up residence in Kansas City.

However, they have one thing in common: they are both experts in their field. Taylor would stop at nothing to help Beyonce, and she will defend the singer until the day she passes away.

Bringing Swifties and the Beyhive together, a source told The Sun that it was ‘the most tightly guarded premiere this year’.

“Crowd control measures were put in place to ensure everyone’s safety because of the stars’ fan bases,” they revealed.

According to insiders, Taylor and Travis have discussed starting a family, and if their “practice run” at his $6 million Kansas City estate goes well, they will move in together permanently.

Just one day after Taylor, 33, concluded up the South American portion of her Eras tour with a sold-out show in Brazil, a moving truck was seen outside the NFL star’s new pad on Tuesday. Inside were pictures furniture and other belongings being carried.

The couple, who began dating in September, is rumored to be ‘obsessed’ with one another, spending a lot of time together by flying to and from her concerts and his games.

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

More than a month has passed since Beyonce opened for Taylor at the Los Angeles venue The Grove for the launch of her Eras Tour.

The Crazy In Love singer stunned on the red carpet wearing a skintight black catsuit paired with a silver chrome breast plate.

Following the premiere, Taylor tweeted a humorous boomerang of the two of them enjoying a bowl of popcorn while seated inside a theater.

She captioned the video, saying, “I’m so glad I’ll never know what my life would’ve been like without @beyonce’s influence.” She has taught me, along with every other artist here, to disobey conventions and break rules in the profession.

Her sense of generosity. Her adaptability and tenacity. Her presence today was truly magical, as she has been a beacon of guidance throughout my career.

Following the Renaissance film’s Los Angeles premiere at the Samuel Goldwyn Theater is Beyonce’s party in London.

Michelle Williams and Kelly Rowland, her bandmates from Destiny’s Child, were among the famous people in attendance.

Additionally, the most recent trailer for the movie featured a glimpse of Beyonce performing an incredible show on stage with the former members.

The LA premiere was a private event, with only the time and the dress code—”cosy opulence”—included on the “save the date” invitations sent to guests.

Variety claims that Beyonce’s guests were only informed of the theater’s location a day before the showing.

According to the article, attendees were instructed to “take a ride share to an address in Beverly Hills, where they were then directed to the screening location.”

Beyonce entered the auditorium as the lights went down, and an announcer informed the audience that no pictures or videos were allowed inside.

The multiple Grammy Award winner stole the show on her big night by wearing a gorgeous silver Versace gown and a rear-length golden wig.

The actress’s ethereal appearance gave rise to claims that she “lightened” her skin, which her mother Tina Lawson refuted last week in a heated Instagram tirade.

In a post published on Tuesday, she angrily said that she was tired of people ‘attacking’ her daughter and lashed out at internet critics.

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

The most recent trailer for the movie showed Beyoncé rejoining on stage for a monumental performance alongside former members of Destiny’s Child, Kelly Rowland and Michelle Williamson; the three was last seen in 2000.

Rather than “celebrating a sister or just ignoring if you don’t like her,” Tina claimed that those who criticize her daughter are promoting “jealousy and racism, sexism, and double standards.”

Mother Tina was among Beyonce’s first guests, along with Lizzo, Janelle Monáe, and Lori Harvey.

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,” according to the official film summary.

On December 1, Beyoncé’s Renaissance: A Film will be released in theaters.
