On a positive note contrasting the challenges facing her company, Yahoo's Chief Executive Officer Marissa Mayer announced that she has given birth to identical twin girls.

Bloomberg reports that Mayer made the announcement via social media website Twitter, saying that she and her family are doing well.

According to the Associated Press, a spokeswoman for Yahoo said that Mayer and her newborn girls are doing fine. However, the she did not reveal the twins' names or birth weights.

This is the second time that Mayer has given birth to children with her husband Zachary Bogue, the first one just months after she took her post at the internet giant. Their first child is a boy named Macallister.

Reports indicate that Mayer's announcement came just a day after she unveiled plans of creating a new company that will hold Yahoo's Internet business.

In the same way that she did when her son was born, Mayer reportedly plans to only have a short break away from work. Back in 2012, she only took two weeks of paid maternity leave, which caused some parents to criticize her for not being a good example to other working moms.

Yahoo, for its part, is generous to new moms, giving a maternity leave that can be as long as 16 weeks.

Her decision, according to Lebenthal Holdings LLC co-CEO Barbara Yastine, makes sense given her role in the company.

Yastine, who has twin girls of her own, said that Mayer is facing pressures both at work and in her personal life, as she is both a company CEO and a mother. “That's fabulous,” she said.

Mayer indeed has a lot of things to face aside from her newborn girls – she still has a big company to lead back into reversing its current decline.

Yet, while many think that Mayer might lose her job in a matter of months, Yahoo company Chairman Maynard Webb said that the company's board still has faith in their CEO.
