(AP Photo/Lionel Cironneau, File) (Newser) – Yahoo CEO Marissa Mayer has just announced she's expecting identical twin girls in December, but don't expect her to be away from work long. "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," despite a ban on the practice, Mayer, 40, writes in a Tumblr post. Mayer drew criticism for taking just two weeks of maternity leave and working from home in 2012, reports CNBC. Mayer says she has no family history of twins but has "embraced the surprise," adding the team at Yahoo is "incredibly supportive and happy for me," per the New York Times.
