On Thursday night, Lance Armstrong hit perennial New York hotspot Marquee for the NASCAR Nextel Cup Series Champions party – and was spotted with a beautiful blonde Ford fitness model named Kim Strother. The two seemed "very into each other," according to an onlooker, who said the cycling champ was very attentive to his new friend. Occasionally during the evening, Strother, "had her arms wrapped around [Lance's] neck," the observer added. At the end of the evening, the pair left together with another female friend.
