The star of The Rachel Zoe Project gave birth to a son named Skyler Morrison Berman in Los Angeles, reports People.
"Mum and Dad 'LITERALLY' (sic) could not be happier or more in love with their son!" the pair said in a statement.
Zoe announced the pregnancy on Twitter last November.
The celebrity stylist recently called her pregnancy "drama-free" and insisted that it has not affected her career.
"I can say in all honesty that being pregnant, working with the kind of people I work with and being this businesswoman has been a really wonderful, drama-free time in my life," she previously said.
