Taylor Swift, who very publicly moved to Manhattan last year — she even became an "ambassador" for the city and included the song "Welcome to New York" on her multi-platinum album 1989 — had a creepy surprise waiting for her when she arrived home on Tuesday. Someone who appears to be a fan left at least 13 notes on the pop star's door yesterday, according to this disturbing post on Instagram.

The 25-year-old singer is photographed regularly coming and going from her downtown NYC apartment. But she’s also — rather brilliantly — opened up her life to her fans in a way that few recording artists of her stature (and sales numbers) do. While most celebs would understandably be a little resistant to forging friendships with their admirers, it’s paid off for Swift — her dedicated fan base propelled 1989 to record breaking sales topping 4 million copies.

She’s invited fans to her Beverly Hills home to hold her cats (Olivia Benson and Meredith Grey, who are almost as famous as she is), staged mini-concerts in her NYC apartment, and even paid off one fan's student loan. (Hey, Taylor we’re fans too!) She shares photos of her Big Apple abode on Instagram, including nights in baking with BFF Karlie Kloss and her birthday party with guests like JayZ, Beyoncé, and Justin Timberlake. She’s also known and loved for interacting with her fans via Twitter, Instagram and Tumblr, leaving kind comments on their posts, offering encouragement, and even giving advice to a fan in the middle of a breakup (and making her a playlist!).
