Put a ring on it: The standout cyclist and veteran rocker met at a charity event in 2003, started dating in 2004 and got engaged in the fall of 2005.
Cancel the cake: Crow was ready to settle down and start a family but Armstrong had already been down that road. At least that's what he later said in his memoir. "She 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."
Crow went on to adopt two boys on her own, while Armstrong would eventually settle down again with Anna Hansen and have two more children, making a total of five Armstrong kids.
