Taylor Swift kicked off the European leg of her RED tour on Saturday night to an excited crowd at London’s O2 Arena. However it was all a bit too much for one fan who stormed the stage for a chance to meet his idol.

Taylor had just finished singing, ‘We Are Never Getting Back Together’, when the enthusiastic fan ran up a flight of steps towards the singer, and appeared to push something into her hand before running back toward the audience. Security guards were swift to act as they grabbed the man when he tried to run back to his seat. Audience members were originally confused, assuming the man was one of the back dancers until he tripped on some steps. The singer herself looked bewildered but didn't seem too shaken with the incident, continuing on with the show once the man had been removed.

The American songstress is playing five nights at London’s O2. On Saturday night she was accompanied by British singer and friend Ed Sheeran who joined her onstage for a rendition of ‘Lego House.’ Taylor performed all her hits including 'I Knew You Were Trouble', '22', and 'Love Story'. Throughout the show Taylor had many costume changes, starting off in a retro red cape dress and at one point appearing in a ringmasters outfit. The show also contained an elaborate set including a staircase as well as numerous backing dancers.

Last night, Taylor was joined on stage by singer Sam Smith for a duet of his song, ‘Money on my Mind.’ The singer was clearly taken by the rising British star tweeting afterwards, “Tonight at the O2, @samsmithworld sang my new favorite song "Money On My Mind" and smashed it! You need this song/artist in your life!”
