Joel Madden says his newborn daughter with Nicole Richie has a healthy appetite.
"She looks so much like her mom it's crazy! She eats like a little maniac and she's really sweet," the Good Charlotte rocker gushes in a post on his DCMA Collective Web site under the heading, "It's a Girl!!!!!"
Harlow Winter Kate Madden was born Friday in Los Angeles, weighing 6 pounds, 7 ounces. She is the first child for Madden, 28, and Richie, 26. The couple began dating in late 2006.
"She barely even cries, even when daddy is changing her diaper," Madden says.
He apologizes for not accepting gifts, cards and phone calls at the hospital.
Madden said he and Richie would like people to donate to The Richie-Madden Children's Foundation.
Richie, the socialite daughter of Lionel Richie, is perhaps best known for co-starring with Paris Hilton in the reality show "The Simple Life."
Last year, she spent 82 minutes in jail after being convicted of driving under the influence of drugs. She was arrested in December 2006 after witnesses reported seeing her Mercedes-Benz sport utility vehicle headed the wrong way on a freeway in Burbank, Calif.
