"As loyal readers of The Zoe Report, I wanted you to be the first to see a picture of the beautiful new addition to our family, Kaius Jagger Berman, aka 'Kai,'" she wrote on Dec. 23. "Rodger, Skyler and I are madly in love and will be happily hibernating for the next couple of weeks. Thank you for all of your kind words, as they mean so much to us."
The Rachel Zoe Project star, 42, also added, "Wishing you and your family a wonderful holiday and Happy New Year!"
In the adorable photo, Zoe sits in a hospital bed while cradling baby Kai and posing with husband Rodger Berman. Despite having just given birth, the fashion designer looks gorgeous with her hair and makeup done.
Zoe announced Kai's birth on Twitter on Dec. 22, writing, "So excited to welcome our baby boy into the world . . . he's 7 lbs 12 oz, beautiful, healthy and we couldn't be happier."
She and husband Rodger Berman, who wed in 1996, are already parents to son Skyler, 2. They confirmed they were expecting their second child in September. "We are beyond excited for Skyler to have a sibling and for us to fall in love all over again," Zoe said in a statement at the time. "We feel incredibly blessed."
