Lance Armstrong 'torn' over break-up

Lance Armstrong closed his weekly radio show on a bittersweet note by playing ex-fiancee Sheryl Crow's song Letter To God.

The couple announced their breakup in a joint statement last week after "much thought and consideration," despite their "deep love and respect." Armstrong said he was "torn it didn't work out".

"Obviously, this week was a rough week for us, but that doesn't change the fact that Sheryl is an unbelievable lady, one of the smartest, wisest, most gifted people I've ever met," he said.
