Lance Armstrong and designer Tory Burch (who bears a striking resemblance to Sheryl Crow, wouldn't you say?) have called it quits on their relationship. "It was a distance thing," said an Armstrong insider. (He's based on Austin; she's in NYC.) But a Burch source disagreed: "Tory would have moved to Texas for him if he popped the question. But he didn't want to commit." Armstrong's rep had no comment.
