Lance Armstrong, 39, has nine-year-old twin daughters and an 11-year-old son to his ex-wife, Kristin Armstrong, whom he divorced in 2003, just as he began dating Sheryl Crow. He and Sheryl Crow became engaged in 2005 but split a year later when Armstrong said, "She wanted marriage, she wanted children ... We're up against her biological clock -- the pressure is what cracked it ... Because if somebody wants a child -- man, that's the greatest gift you can give to a woman -- so who are you to stand there and say I don't want one ... So we were at different points in our lives. We were not compatible on that issue."

But in July 2008 Armstrong began dating Anna Hansen, whom he met " through his work with the charity where she works, First Descents, a non-profit that works with cancer survivors," reports the UK's "Daily Mail." In 2009 Hansen and Armstrong welcomed a son, Maxwell, now 16 months. Then on October 19, 2010, they're celebrating the arrival of daughter Olivia Marie. Lance Armstrong tweeted this morning: "Olivia Marie Armstrong has arrived!" He also posted, "Thanks to you all for the support and well wishes. Momma and Olivia (@Cincoarmstrong!) are doing great. She's a beauty." Lance Armstrong explained on Twitter that he's nicknamed Olivia "Cinco" because she's the fifth of Armstrong's offspring!

In 1996 doctors diagnosed Lance Armstrong with advanced testicular cancer that had spread to his lungs and brain. After immediate and extreme treatments, Armstrong was determined to be cancer-free in 1998. The cancer and treatments were thought to have ruined his chances at having children...so indeed Olivia and every Armstrong infant arrival are awesome news to us all!
