Kate Hudson, Lance Armstrong, Chris Robinson And Kids Spend Father's Day Together

Kate Hudson's four-year-old son Ryder went to a Father's Day brunch with her new beau Lance Armstrong -- and dad Chris Robinson.

With their kids in tow, Hudson and Armstrong split into two cabs for the ride from the actress' New York City home to Brooklyn restaurant Frankie's 457.

"There was a boys' cab and a girls' cab," an onlooker tells Usmagazine.com. "Ryder went with Lance.

"He was very comfortable with Lance," the onlooker adds. "He ran right towards him!"

The actress and the cyclist -- who were also spotted in Toronto over the weekend at a charity bike race -- put the focus of Father's Day on their young kids. (Armstrong has a son, Luke, 8, and twin daughters Isabelle and Grace, 6, with ex-wife Kristin, whom he split from in 2003.)
