Taylor Swift paid $17 million for her new Rhode Island home, but lately it seems more trouble than it's worth, what with crazed fans swimming up to the manse and all.

To combat this, T-Swizzle (or more likely someone who works for her) posted cheeky "No Trespassing" signs around the property -- with references to her hit single 'Trouble.'

The informal looking sign boasts the words, "I knew you were trouble when you walked in. NO TRESPASSING," warning visitors that if you walk on her land, not to mention her heart, she will mock you for it with a hit song. And possibly a call to the authorities.

Not so amused? Locals who are annoyed that Swift's hired goons patrol the area and won't allow even area residents on nearby public beaches.
