Fashion designer, stylist, and reality star Rachel Zoe announced, via Twitter, that she and her husband Rodger Berman welcomed their newest bundle of joy on Sunday, December 22. “So excited to welcome our baby boy into the world…he’s 7 lbs 12 oz, beautiful, healthy and we couldn’t be happier,” Zoe wrote.

The couple confirmed that they were expecting their second child back in September. “We are beyond excited for Skyler, 2, to have a sibling and for us to fall in love all over again,” Zoe said at the time. “We feel incredibly blessed.” She also went on to talk about Skyler’s thoughts on having a new edition to the family. “It depends what day you ask him. Right now he just doesn’t want anyone near Mommy except him, so I don’t know when that should change,” she said.

Zoe later took to her personal blog to announce the name of her new little boy, Kaius Jagger Berman, aka “Kai”. Along with a picture of her happy family, Zoe posted a message to all of her fans, thanking them for their support and wishing them a Happy New Year.
