The skinny little twig, Nicole Richie gave birth to a healthy baby girl, People reports:

"We are very blessed she's healthy and beautiful and so good already," Madden told PEOPLE on Saturday. "We are very happy."

Richie, 26, and Madden, 28, welcomed 6-lb., 7-oz Harlow Winter Kate Madden on Friday, the couple's rep at Handprint Entertainment says, and the Hollywood congratulations started flowing.

"It's just amazing. I'm so excited," Richie's friend, The Hills star Lauren Conrad, told PEOPLE while at the grand opening for Jimmy Choo's Flagship store in Beverly Hills. "I want to see the baby! I bet it's beautiful."

Congratulations and best Wishes!
