Jacob Kulke, 24, was accosted by the country singer's security guards after clambering over the wall and gate of her Nashville, Tennessee, home, according to the Daily Star.

The obsessed fan is said to believe he is in a relationship with the star and allegedly claimed he wanted to spend the day with "girlfriend" Taylor on her 23rd birthday last week.

However, Taylor was thousands of miles away in the UK with current beau, One Direction star Harry Styles.

The American singer recently spoke of her stalker woes admitting she still gets nervous when her minders send her pictures of crazed fans in a bid to warn her.

She told Cosmopolitan magazine: "I get nervous when I have stalker incidents. I try not to talk too much about it because it scares me. Sometimes you get a dude who kind of wants to steal you.

"That's why I'm so grateful I have people looking after me, like [bodyguard] Dennis. Over the past couple of years it's got worse. I get told if there's been an attempt or a threat.

"My security text me a picture and say, 'Look out for this dude; he's driven across the country, he's off his meds,' or something like that."
