Taylor Swift wore a bikini last week while Down Under with her pals. On Thursday, she and a couple girlfriends broke out their suits at Cottesloe Beach in Perth. Taylor's fun in the sun came during a break from a string of shows in Australia. She was in Adelaide for a concert on Sunday, but managed to break from the stage last night to mark her father's 60th birthday. In addition to her performances and family parties, it was a big weekend for Taylor because Dr. Seuss's The Lorax opened back home in the US. The Lorax topped the box office, giving Taylor one more reason to celebrate during time off from her tour.
