Healthy Living with Gwyneth Paltrow

Like other moms with small children, Gwyneth says she and Madonna often get together for playdates at home or in the park. "I'm very, very involved in [my kids'] lives and what they're doing and where they're going," she says. "I take them to the park and meet other parents."

Gwyneth says Madonna's children, Lourdes, Rocco and David, her adopted son from Malawi, represent their mother's greatest qualities. "Her children are beyond," Gwyneth says. "You can measure somebody by their children ultimately, and these children are phenomenal. ... They're very polite. They're sweet, kind, conscientious."

At home, Gwyneth says 3-year-old David likes to perform dance routines from Madonna's concerts on the living room floor. When the kids get together, Gwyneth says her son Moses likes to listen to his father, Chris Martin's, Coldplay tracks, while David prefers his mom's music. "It's very funny," she says.
