Sheryl Crow hung out in Venice Beach, CA, with her sons, Wyatt and Levi, yesterday. The trio played in the sand and later rode around the boardwalk on bicycles. Sheryl let loose with her boys after getting caught in the middle of her ex Lance Armstrong's doping controversy, which he finally admitted to in an interview with Oprah Winfrey that aired last week. Sheryl told Entertainment Tonight that she thinks "that honesty is always the best bet and that the truth will set you free. To carry around a weight like that would be devastating in the long run." Sheryl added of Lance, whom she dated from 2003 to 2006, that "I know how hard he worked to win those titles, and you know, it was hard to watch." Sheryl isn't just in the spotlight because of Lance's drama, though. Since she's also an adviser on The Voice this season and will be working with Blake Shelton's team.
