Lance Armstrong is dating N.Y.C. fashion designer Tory Burch. The couple have been quietly dating for months, according to sources. "They are very much a couple," says R. Couri Hay, a friend of the designer’s.

Reps would not comment on the relationship. A friend says Armstrong contacted Burch after reading her profile in Vanity Fair. The friend adds Burch has visited Armstrong in Texas several times.

Most recently, the couple cozied up at Houston’s Hotel Derek on March 6, where they drank margaritas before heading off to a reception in Burch’s honor. Also in town at the time was Armstrong’s ex-fiancée Sheryl Crow, who bears a striking resemblance to Burch. The longtime couple called it quits in February 2006.

Another source says of Armstrong and Burch, "I can’t say whether it’s long-term, but they’re having a great time."
