Maisie Peters is finally at the age where she can make good use of Taylor Swift's '22.'

The British songstress had a grand celebration on her 22nd birthday. She played a stadium on the day alongside Ed Sheeran and even had 60 thousand concert attendees wish her on her special day.

But the fun didn't end there, as the party continued behind the curtains even after the concert ended.

Maisie Peters Wished a Happy Birthday by 60 Thousand People

On May 28, 2022, Peters turned 22. And she spent her special day with her friends, attending and performing alongside Sheeran at a concert in Cardiff, and making TikToks.

"went to an ed sheran [sic] show for my birthday," she wrote on her birthday post on May 28. Alongside, she posted a picture and a video from the concert.

The picture was just of her, elated with the experience. The video was of Sheeran, on stage, announcing that it was Peters's birthday.

He then urged the 60 thousand attendees to sing 'Happy Birthday' to the songstress. Peters's expressions suggested she could not believe what was unfolding in front of her.

The comment section of the post, too, was filled with birthday wishes for the now-22-year-old.

To those of you who don't know, Peters is a twin. So, this means her twin sister, Ellen, too, celebrated her 22nd trip around the sun on the day.

Maisie Peters's Birthday Celebration — Taylor Swift Hit, TikTok, and Booze

Peters uploaded the same video to her TikTok but added a few words, revealing her experience.

"real or not 60,000 people sang me happy birthday last night," she wrote over the video. In the caption, she detailed, "i cannot even begin to explain last night other than it was the best night of my life,"

The overlay text also revealed her alcohol and Swift-filled celebrations afterward. "then we all did vodka shots and ed sheran [sic] and my girls moshed to 22," she wrote. "i think i might still be drunk."

Right before this video, she posted another video where she and her friends were jumping to Swift's perennial birthday hit, '22,' in the middle of an empty Cardiff stadium.

"I have been waiting my whole life to sing this song and mean it," she wrote in the overlay as she expressed that playing at a stadium on her 22nd birthday "felt right."

Her last post on TikTok was also a birthday celebration. She and her girlfriends made a choreographed dance TikTok on 'We're All In This Together' from High School Musical. They danced on the stairs of the stadium, presumably after everyone had left.

After everything was said and done on May 28, she took to her Instagram stories to recap the entire day on May 29.

"last night was actually the most feral thing to ever happen," she wrote her recollections over a selfie of her gang. She said some of her friends were still drunk, everybody had cried, and one of her friends even almost "threw up on the side of cardiff bridge."

Peters is still touring with Sheeran and has been playing venues all over the place. She first worked with Sheeran before releasing her debut album, You Signed Up For This and is signed to his label, Gingerbread Man Records.
