Yahoo Inc Chief Executive Marissa Mayer announced she is pregnant with identical twin girls, likely due in December.
Not that it's going to slow her down much.
"Since this is a unique time in Yahoo's transformation, I plan to approach the pregnancy and delivery as I did with my son three years ago, taking limited time away and working throughout," Mayer wrote in a blog post on Tuesday.
Mayer's pregnancy comes at a critical time for Yahoo, which is preparing to spin off its stake in Chinese e-commerce giant Alibaba Group Holding Ltd and considers the future of its holding in Yahoo Japan Corp.
Mayer, 40, was pregnant when she joined Yahoo as CEO in July 2012 and she gave birth to a baby boy in September that year.
