While most girls her age are spending their disposable income on movies and makeup, superstar singer Taylor Swift, 20, has just plunked down nearly $2 million on a luxurious penthouse in her favorite city in the world: Nashville. “I’m so excited!” says Taylor of the 4,062-square-foot, three-bedroom home she has recently purchased in the swanky Adelicia condo development. Located just minutes away from the city’s downtown area, the high-tech condo has 24-hour concierge service, tight security and lots of space for a young, single superstar to relax between world tours. “I love Nashville,” says Taylor, who grew up on a Christmas tree farm in Pennsylvania with her parents and younger brother, Austin, but always longed to live in superstardom. “I never expected that all this would happen to me,” says Taylor, who still loves living as normal of a life as possible. Fans often see her cruising local roads or shopping around town. “I love Target and Walmart — I find the coolest things there,” she says. The star, who describes her tastes as girlie, says she’s looking forward to decorating her bachelorette pad in a “quirky, whimsical style,” when her current tour for her second album, Fearless, winds down in June. “I love interior designing,” she says.
