Though rumors continue to swirl around the company she helms, Marissa Mayer has something to smile about today: The Yahoo CEO announced early this morning that she gave birth to identical twin girls.

Tagging her husband, Zack Bogue, one of the most powerful women in tech announced the good news to her 1.14 million Twitter followers a little after 9 a.m. PT:

On her Tumblr (the platform Yahoo bought for $1.1 billion in 2013), Mayer elaborated that "Zack and I are excited to announce that our identical twin girls have arrived! They were born early this morning. Our whole family is doing great! Thanks to everyone for all of the support and well wishes throughout my pregnancy."

Mayer's son, Macallister Bogue, was born in 2012 shortly after she left Google for Yahoo. As with that birth, Mayer says that she will take two weeks off before returning to work.

In a post announcing her pregnancy in September, Mayer wrote "I plan to approach the pregnancy and delivery as I did with my son three years ago, taking limited time away and working throughout."

"Moving forward, there will be a lot to do for both my family and for Yahoo; both will require hard work and thoughtful prioritization," she wrote. "However, Iā€™m extremely energized by and dedicated to both my family and Yahoo and will do all that is necessary and more to help both thrive. The future looks extremely bright on both fronts."

The birth of Mayer's two girls (names as yet unknown) took place, we must note, just ten days after the arrival of Mark Zuckerberg and Priscilla Chan's daughter Max. It's a tech titan baby bonanza!
