HILARY DUFF, WATCH OUT. Ashlee Simpson (backup tracks and all), move over. Carly Patterson has set her sights on a new goal: pop star. Yes, the 2004 Olympic gold medal-winning gymnast will be hitting the studio next month in New York to see how she sounds on some tracks. Patterson, who has risen from beginning tumbler to best in the world in 10 years, should not be counted out from achieving anything. So, it wouldn't surprise many to soon read that she is earning gold records instead of gold medals. In the meantime, Patterson is already spending her days and nights on a "rock star" tour bus and seeing the nation. Patterson, 16, was in town last week to publicize Friday's stop in the Spokane Arena for the 42-city TJ Maxx Tour of Gymnastics Champions. The event showcases the USA's top male and female gymnasts in an exhibition format. On Tuesday, she arrived from a morning media stop in Boise and flew to Spokane, where she closed her day with a similar event. On Wednesday, she did more media events and fielded questions from students at St. John Vianney School in the Spokane Valley before getting on a plane to San Jose.
