Fan Jacob Kulke, 24, was caught on the grounds of the 'Red' hitmaker's property in Nashville, Tennessee, in the early hours of Friday morning after travelling from Wisconsin to spend the day with Taylor - who was not at the property - for her 23rd birthday, according to a report.
TMZ reports that security spotted Jacob and detained him until the police arrived at 1.45am, where he told them he was "the boyfriend of the homeowner".
He reportedly continued to tell police he had spoken to someone at Taylor's home via social media before hopping on a bus to see her after her birthday, which was on Thursday.
Jacob has been arrested and is being held on a $10 000 bond, and it has been reported he has a criminal past of battery, disorderly conduct and possession of drugs in his hometown of Wisconsin in 2010.
Taylor has been in the UK for the past week with her boyfriend, One Direction star Harry Styles.
The romantic 18-year-old singer bought her 23 cupcakes for her birthday, a designer handbag and took her for a romantic meal in the George & Dragon Pub in Great Budworth village.
Earlier in the week, the couple enjoyed a trip to tourist spot the Lake District with Harry's parents and they shopped for Christmas presents in Bowness-on-Windermere, Cumbria.
