Actress Kate Hudson has fueled reports she is dating cyclist Lance Armstrong, after allegedly making their romance public at a party in Cannes, France. The couple was said to have danced and kissed at designers Dolce & Gabbana's annual bash on Friday. According to People.com, Hudson and Armstrong danced away to old Madonna songs and other 1980s classics, in front of other celebrities including Natalie Portman, Lindsay Lohan and supermodel Naomi Campbell. A source says, "They were beaming at each other. So cute." Hudson split from actor Owen Wilson earlier this month, while Armstrong was previously engaged to singer Sheryl Crow.
