Taylor at BBCR1

TAYLOR, OUT OF COUNTRY: Big Machine megastar Taylor Swift dropped by BBC Radio 1's Live Lounge to perform her new single, "Shake It Off," and more; she also chatted with the Beeb's Fearne Cotton about London, her fans and of course her cats. "The really fuzzy one," she noted of her family of felines, "is called Borchetta. Apparently a lot of people want to buy his litterbox." (10/9p)
