The singer, who is overseas, turned 23 Thursday. Court documents show 24-year-old Jacob Nicholas Kulke, of Marshfield, Wis., was arrested early Friday after climbing a fence and secured gate.
The affidavit did not identify the property owner, and Swift's spokeswoman declined comment on whether the home was linked to the family. But online celebrity news websites indicate Swift had a connection to the home. The City Paper previously reported that the $2.5 million house in Belle Meade, a Nashville suburb, was bought last year by a trustee who has previously handled property deals for Swift.
The affidavit said Kulke claimed he was in contact with a person at the home through "social media" and it was her birthday and he wanted to surprise her and that he was also dating her.
"He continuously stated once he was released, he was going to continue to have contact" with the people at the home, the affidavit said.
A lawyer for Kulke did not immediately return a message left by The Associated Press.
He was charged with criminal trespassing and his bond was set at $10,000. Nashville police said in a news release that Kulke is also wanted in Colorado for contempt of court and probation violation in regard to a burglary case. He also has misdemeanor charges of battery, disorderly conduct and possession of THC from 2010 in Wisconsin, according to court records.
Nashville police say Colorado authorities have indicated they will plan on extraditing Kulke back to the state once the trespassing charge is adjudicated.
