Yahoo CEO Marissa Mayer announces she's given birth to twin girls

Mayer announced the news after fielding questions about the complex deal to sell Yahoo's core businesses on a public call with investors Wednesday

Marissa Mayer has given birth to twin girls just one day after announcing a complex corporate "reverse-spin" maneuver designed to reverse the long, slow decline of the technology company.

Mayer wrote in September that she would not be taking much time off after the birth of her children. "I plan to approach the pregnancy and delivery as I did with my son three years ago, taking limited time away and working throughout," she said on her Tumblr (a company also owned by Yahoo). "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."
