Marissa Mayer made the announcement Thursday on Twitter. She and her husband also have a 3-year-old son.
Yahoo CEO Marissa Mayer has given birth to identical twin girls.
Mayer made the announcement on Twitter Thursday and said the "whole family is doing great."
Mayer and her husband announced they were expecting back in September, and Mayer said she would only be "taking a limited time away and working throughout" her pregnancy. (Video via Fortune)

This is definitely a hectic time for Yahoo. The company just announced plans to spin off its core business, and some have questioned Mayer's leadership.
