It was certainly an eventful week for Taylor Swift.  Not only has T-Swizzle been cavorting around England with latest boyfriend Harry of One Direction, but she also celebrated her 23rd birthday!  And on her 23rd birthday, some maniac across the pond broke into her Nashville home claiming to be her friend & that he was invited via social media to her home for her birthday celebration.  Needless to say, he was arrested.  Taylor also world premiered the video for her new song "I Knew You Were Trouble" on her birthday.  Check out the video below, followed by a video of Taylor's bff Selena Gomez dancing to to "I Knew You Were Trouble"...
