Japan-based South Korean singer BoA (21, profile) appeared at a press conference yesterday with both her left arm and left leg in plaster. The event, held at a hotel in Seoul, was to promote her assault on the U.S. pop market, but the attention of the 200 gathered reporters was immediately focused on her barely concealed injuries. She suffered a broken arm and a fractured leg the previous day when she fell down a set of stairs after a meeting at her MS Entertainment management office in the Korean capital. She was rushed to a nearby hospital, where she was told the break would need about six weeks to fully heal. But she was upbeat about the accident, saying she was grateful it didn’t happen closer to her upcoming U.S. debut. She is due to release the single “Eat You Up” through iTunes and MySpace on October 7 and in stores on November 11. She has been preparing for the last couple of years, even going to New York to take English and dance lessons. BoA first came to Japan to launch her pop career at the tender age of 14, and she quickly became one of the first artists to achieve the crossover.
