While Lance Armstrong hit the links for the celebrity golf tournament in Tahoe yesterday, his girl Kate Hudson stayed on the sidelines to enjoy the sun. Even if she didn't participate in the game, she had her share of fun at the night before party. Earlier this week it was all about the tennis camp for the couple and their three kids between them, but apparently Kate's ex Chris Robinson also got in on the fun watching his son Ryder from the sidelines acting buddy-buddy with Lance. Between the time on the court and the course, Kate and Lance are loving the Summer sports — now I just wonder if she's nervous showing off her bike skills to her new man.
