SHERYL CROW IS UPTIGHT - Sheryl Crow doesn't approve of her ex-boyfriend Lance Armstrong dating Ashley Olsen. Presumably because Lance is 36 and Ashley is 21. Life and Style says, "Sheryl rolled her eyes and said, 'That's pathetic. Ashley's a kid.' " Whatever. Sheryl is just jealous because she's 45, and now her ex is stabbin someone half her age.
