Britney Spears refueled with another drink from Starbucks while shopping in Calabasas, CA, last night. It was the singer's latest trip to the stores, after also stepping out to browse Monday. She's spending some of the cash she made over the last year, though it'll be hard to make a dent in her forture considering her recent ranking as one of Hollywood's top-earning entertainers. Part of Brit's financial success comes from her mini-empire of fragrances, and it turns out that her fellow pop star Taylor Swift is a fan. Taylor recently spoke to Allure about wearing one of Britney's scents while in high school. Miss Swift said, "The coolest girl in school wore Britney Spears' Fantasy, and I had to copy her."
