The seven-time Tour de France champ Lance Armstrong confirmed his engagement to Grammy-winning singer-songwriter Sheryl Crow on Monday. The cyclist proposed to Crow on Wednesday, August 31st, in Sun Valley, Idaho. The couple have been dating since they met at a charity event in October 2003.

Crow will release her fifth studio album, Wildflower, on September 27th, and has revealed that the album's title track was inspired by Armstrong and his three children (with ex-wife Kristin). "It's kind of a reminder, particularly when you look at his young children, how they gravitate to goodness and to light," says Crow. "The idea of the song is that no matter how chaotic it is, wildflowers will still spring up in the middle of nowhere."

Though no definitive plans have been set, Armstrong's spokesman says a spring wedding is likely. This will be the first marriage for the forty-three-year-old rock star and the second for the cyclist.

In the meantime Crow will hit the road in support of the release, playing a string of dates beginning October 16th in Seattle.
