When Catherine, Duchess of Cambridge visited the seaport town of Grimsby, England yesterday, she may have let it slip that she's having a little baby girl, People reports. And that got us thinking, wouldn't that be lovely? After all, the Palace changed the rules in 2011 to allow a first-born female to be the heir to the throne, which means the mixed chromosomes of Kate and Will would be more than a Princess, she'd be the Ultimate Power Girl. And she'd be impeccably dressed, with a fashion-loving mom to teach her the chic-but-not-overspending ways of Zara, Topshop, and Reiss. Plus, just think of the potential mommy-and-me outfits (as seen on another British mother-daughter-duo, Victoria and Harper Beckham). But that's just our two cents. What do you think? Tell us if you think Kate's having a boy or a girl in the poll below.
