Julia Roberts Pictures: Julia Roberts visits the "Late Show with David Letterman" at the Ed Sullivan Theater on August 4, 2010 in New York City.
Roberts, who recently told Elle magazine that she doesn't believe in Botox, was asked by the host how she keeps her "kid" looks.
"Thank you," replied Roberts, who next appears in "Eat Pray Love." "It's the love of a good man, good kids. I eat a lot."
The actress also took the opportunity to set the record straight about varicose veins, mistakenly mentioned along with her name in the show's intro.
