Tour de love: Kate Hudson and Lance Armstrong kiss outside a Santa Monica gym
Passionate: The couple couldn't keep their hands off each other
It's the second time in a week they've struggled to keep their hands off each other - they were spotted kissing on a Brentwood tennis court during a doubles match on Sunday.
The seven-time Tour de France champion, who has previously romanced singer Sheryl Crow, fashion designer Tory Burch and actress Ashley Olsen, has so far dodged questions about his latest relationship.
During a recent appearance on US talkshow The View, he said: 'I know you have to ask that question . . . and it's my right not to answer it.'
Kate is also playing coy, saying: 'It's better to let ... people speculate as much as they want to speculate.'
