Lance Armstrong and Kristin Richard
A year after being diagnosed with cancer, Lance Armstrong met Kristin Richard. The couple got married soon after and, for six years, seemed entirely happy together. However, Armstrong then decided he wanted to have an affair with singer Sheryl Crow.
Unfortunately, this meant getting a divorce from the woman who supposedly loved him no matter what. Kristin Richard did get $14 million in the settlement, so she was hardly left with nothing. Even if she may have had a broken heart, at least she got something out of it financially.
