Marissa Mayer Just Announced She Gave Birth to Twins

Marissa Mayer, president and CEO of Yahoo, announced the arrival of her identical twin girls this morning. She tweeted the news early Thursday morning.

Her twin girls arrive just a little over a week after Mark Zuckerberg and Priscilla Chan's baby, Max, was born. Mayer's initial announcement of her pregnancy and decision to take "limited time away" prompted widespread debate about maternity leave.

It's unclear just how much time Mayer will take for maternity leave, but whatever she decides to do, congrats all around!
