Marissa Mayer, Yahoo CEO, Expecting Twin Girls

Marissa Mayer, CEO of tech giant Yahoo, is expecting twins, the Los Angeles Times is reporting. She’ll be the proud mother of twin girls, likely in December.

Mayer, 40, announced her pregnancy on her Tumblr account; Tumblr is, of course, owned by Yahoo.

“With great happiness, [my husband] Zack and I have some exciting news to share – I’m pregnant! In fact, I’m expecting identical twin girls, likely arriving in December.”

And like a true CEO, Mayer crunched the numbers before making a big announcement.

“The twins part was quite a surprise, because I have no family history of twins or any other predisposing factors. However, as I’ve now learned, identical twins occur by random chance in roughly 1 out of approximately every 300 pregnancies.”

The twins will be the second and third children for Mayer and husband Zachary Bogue; the couple have a 2-year-old son.

For a while in 2012, according to MSN, Mayer’s pregnancy with her son actually became something of a metaphor for the plight of working moms across the country. Announcing her pregnancy on the same day that she was named CEO of the struggling Yahoo, Mayer’s appointment raised questions about whether or not she would be able to handle juggling the demands of being a mother with the demands of helming a billion-dollar corporation through difficult times. In fact, she only took a few weeks for maternity leave when her son was born.

Mayer went on to raise eyebrows when she returned to work, building a nursery adjoining her executive suite at Yahoo headquarters, while at the same time banning employees from telecommuting — an option that many working moms in Yahoo’s employ would have found a lifesaver. While critics called the move contradictory, Mayer herself stood by her decision, insisting that allowing workers to telecommute was “not what’s right for Yahoo what right now.”

Still, things have improved for working parents at Yahoo under Mayer’s leadership, according to Yahoo News. In 2013, the tech giant began offering up to 16 weeks of paid leave for new mothers, and up to eight weeks of paid leave for new fathers. Prior to Mayer’s appointment as CEO, mothers could only take eight weeks, while fathers had none.

Like she did with her first pregnancy, Mayer doesn’t plan to take much time off work after her twins are born, saying on Tumblr that she only plans to take “a couple weeks” of maternity leave.
