Larry Page, the dorkier half of Google's founding duo, has mastered at least one basic human function: His wife, former model and Stanford bioinformatics Ph.D. Lucy Southworth, is pregnant.

Took him long enough. The pair married in December 2007, with Page (net worth $18.6 billion) planting a kiss on his bride on Richard Branson's exclusive Necker Island. Co-founder Sergey Brin and his wife, Anne Wojcicki, have already popped out a billionaire baby boy. We wonder: Will the Pages go with a squad of Stanford-trained nannies, or take their child to Google's gold-plated childcare?
