Kate Hudson dating Lance Armstrong?

Kate Hudson is reportedly dating Sheryl Crow's ex-boyfriend Lance Armstrong.

The actress -- who recently split from her on/off boyfriend Owen Wilson -- is said have embarked on a passionate affair with the 36-year-old seven-times Tour de France winner.

A source said: "Kate and Lance have been dating for a couple of weeks. She thought it was funny when people were writing recently that she was engaged to Owen because the reality was that they had split again and she was secretly seeing Lance.

"She and Lance are both physical, passionate people – she's never been happier."

Hudson -- who on Friday flew to join Lance at his home in Austin, Texas, for a romantic weekend together -- started dating the retired cyclist after sparks flew at a private New York dinner party.

The source added: "They have known each other for a while and Lance is one of Owen's good friends.

"When Kate was with Owen, she got to know Lance really well but they hooked up again recently at a dinner party thrown by a mutual friend and that's when the romance began. They have both been keeping it very quiet."
