Trespasser with knife arrested at Taylor Swift's Nashville property at 2am

 – A man was arrested overnight for allegedly trespassing at a home linked to Taylor Swift.

24-year old Jacob Kulke was booked at around 2 a.m. Friday on a criminal trespassing charge. According to an affidavit, Kulke went to the estate in Belle Meade, climbed a fence and a secured gate.

When he ran into security he claimed that he was in contact with the person at the address through social media, that he was dating her and that he wanted to surprise her for her birthday. Incidentally, Taylor celebrated her 23rd birthday on Thursday.

He claimed he had taken a bus from Wisconsin, and then a taxi from the Nashville bus stop. Police also said he had a knife on him when he was arrested.

Taylor Swift reportedly purchased the 6,000 square foot mansion for family members last year, although it is listed as being purchased by a trustee named Michael J. Moore.

The affidavit indicates that IT personnel confirmed there had not been any "social media" contact between Kulke and Swift; however, NewsChannel 5 discovered a Twitter believed to belong to Kulke where he wished her "Happy Birthday" on Thursday.

Swift recently told Cosmopolitan about her problems with stalkers. "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. No one has ever been successful in getting into my house or anything like that. I have an amazing security team.”

"I just try to be safe and be conscious of people around me. It’s something you just have to deal with. It’s the price you pay for getting to do what you love. You can let it take over your life and make you fearful all the time, or you can live your life in spite of it.”

Kulke has a criminal past -- TMZ has learned he was convicted of battery, disorderly conduct and drug possession in Wisconsin back in 2010. He was placed on 13 months probation.He had previously been arrested for second degree burglary in Colorado, and there is a warrant out for his arrest in Colorado for a probation violation.

He was held in the Davidson County jail on $10,000 bond.
