Star cyclist Lance Armstrong is dating musician Sheryl Crow - and not Sandra Bullock. Widespread reports had the five-time Tour De France sporting hero hooked up with the Miss Congeniality star, and that he'd given her an inscribed bracelet. But Armstrong is instead smitten with "Soak Up The Sun" singer Sheryl, and the two have been dating since meeting last month at Andre Agassi's Grand Slam for Children event in Las Vegas last month . A source says, "Lance was amused to hear about the bracelet as Sheryl's the one who has him hooked."
