Singer Sheryl Crow has told "Entertainment Tonight" that it would have been difficult for her ex-fiance, former cycling champion Lance Armstrong, to keep his doping secret any longer.

"I think that honesty is always the best bet and that the truth will set you free," Crow told ET's Nancy O'Dell. The musician told ET she only saw "bits and pieces" of Armstrong's confession interview with Oprah Winfrey. "To carry around a weight like that would be devastating in the long run."

Armstrong and Crow dated from 2003 until splitting in 2006.
