Turns out Mayer, 37 — who became the Fortune 500’s youngest CEO and scored a $71 million pay package at Yahoo — stunned us even more when she called back after Yahoo announced her appointment: “I’m pregnant,” she said.

Fortune broke the story of Mayer’s pregnancy. (She’s due October 7, and it’s a boy.) And she fueled the debate about whether successful working women can have it all.

The debate was already raging, actually, since last month when Princeton University’s Anne-Marie Slaughter wrote “Why Women Still Can’t Have It All.” Slaughter’s Atlantic cover story critiqued stars like Facebook COO Sheryl Sandberg who seem to do it all (with domestic help) and dare other aspiring women to try.

Let’s continue the debate. It’s healthy. And let’s hope that other women like Mayer and Sandberg — women who succeed at work and family — surface as role models, as more corporate boards open up opportunities.
