Kristin Armstrong on Oprah; whatever happened to Lance?

Every divorcee's nightmare will come true for Lance Armstrong on Tuesday as his ex-wife Kristin visits the Oprah Winfrey Show and dishes with Oprah about their marriage and “why it ended” (check local listings).

Update: Here's the former Mrs. Armstrong in Glamour's Sex & Love column. Hat tip to my wife (I swear!).

Meanwhile, Armstrong has not settled into a quiet retirement, sitting lazily around the ol' fishing hole. The 7-time Tour winner, whose philanthropic battle with cancer is featured in a cover story in this week's Sports Illustrated (cover), is in Belgium taking in a couple of stages of the Giro this week, then will participate in Livestrong Day May 17. On May 28, he'll strap into a special Corvette Z06 pace car as he paces the Indianapolis 500.
