The media mogul announced the news via Twitter this morning (of course), saying that she and her daughters were doing well:
Mayer will famously be taking only two weeks maternity leave, as she did with her first child, son Macallister.
The 40-year old announced her pregnancy in September, saying the twins were "quite a surprise."
"I have no family history of twins or any other predisposing factors," Mayer explained at the time. "However, as I've now learned, identical twins occur by random chance in roughly 1 out of approximately every 300 pregnancies. Zack and I have embraced the surprise and are very excited about these new additions to our family.
"Since my pregnancy has been healthy and uncomplicated and 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. I've shared the news and my plans with Yahoo's Board of Directors and my executive team, and they are incredibly supportive and happy for me."
Just last week, Facebook CEO Mark Zuckerberg welcomed a daughter with his wife, Priscilla Chan.
No word yet on whether the CEOs will be meeting up for playdates, but stay tuned.
