When Sheryl Crow dumped Lance Armstrong in 2005 because he didn't want more children, she probably didn't envision him getting someone else pregnant only four years later. As Armstrong reveals in his new biography, Lance, Crow "wanted marriage, she wanted children; and not that I didn't want that, but I didn't want that at that time because I had just gotten out of a marriage, I'd just had kids... Yet we're up against her biological clock—that pressure is what cracked it." Two years after their split, Crow adopted a baby on her own. Armstrong went on to date Kate Hudson and Ashley Olson, among others, before settling down with Anna Hansen, who will have his fourth child next month.
