FameFlynetUK/FAMEFLYNET PICTURES It's no secret Taylor Swift has a very passionate fanbase—but one overzealous admirer seems to have gone a bit too far during a recent concert.
After singing her hit tune "We Are Never Ever Getting Back Together" during her show at London's O2 Arena on Saturday, Feb. 1, where she kicked off the European leg of her Red tour, an obsessed fan suddenly rushed the stage to approach the singer.
The male fan, who was much larger than the singer, ran up a flight up stairs towards Swift before seemingly pushing something into her hand and coming face to face with the 24-year-old pop star.
(And no, it wasn't One Direction's Niall Horan, who was spotted in the audience that night.)
While we would expect the moment to be a bit terrifying for T.Swift, the blonde beauty seemingly had a smile on her face during the impromptu fan encounter before the man rushed back down the stairs and was mobbed by security.
Saturday's show was the first of the "Love Story" singer's four performances at the O2 arena. She'll be taking the stage in London again on Tuesday, Feb. 4, Monday, Feb. 10 and Tuesday, Feb. 11.
Luckily, the unruly fan didn't dampen Swift's post-show mood, as she took to Twitter after her performance, thanking pal Ed Sheeran for sharing the stage after the twosome teamed up on his hit "Lego House".
"First night in London and @edsheeran came out to surprise the crowd with 'Lego House'. Earth-shattering screams ensued. What a lad. #redtour," she wrote.
And Sheeran reciprocated the social media love, "Sung Lego house for the first time ever with a band tonight with @taylorswift13 at her London show. Orsum, thanks for all the love," he wrote.
Leave it to Swift to perform like a pro.
