Lance Armstrong, Kate Hudson Romance Blossoms

The budding romance between actress Kate Hudson and cycling superstar Lance Armstrong seemed to be sizzling this weekend, with the pair spotted leaving a Monaco hotel and embarking on a boating trip.

The exes of Owen Wilson and Sheryl Crow were reportedly kissing and snuggling at a Cannes Film Festival party hosted by Dolce & Gabbana on Friday, days after they'd been seen riding bicycles together, the New York Daily News reported.

Hudson, 29, and Armstrong, 36, were also caught leaving a hotel in Monaco and setting off on a boating excursion, according to the U.K.'s Daily Mail.

"Kate and Lance have been dating for a couple of weeks," a source told the Mail. "She and Lance are both physical, passionate people. She's never been happier."

The couple reportedly met through Wilson, according to the News, but started their relationship after spending time together at a dinner party in New York.

Hudson and Wilson had recently reconciled but split again. Armstrong ended his engagement to Crow in 2006.

Ironically, it isn't the first time Armstrong has moved in on an ex of Wilson's: Crow and Wilson were also an item at one point.

Wilson was hospitalized last year after attempting to commit suicide.
