Female Royal Heirs

Ever since we found out that Kate Middleton is pregnant, we've been dying to know if Prince William and his wife will be having a boy or a girl (or twins!). Today we got a teensy hint that the Duchess of Cambridge is expecting a girl during a visit to the National Fishing Heritage Centre in Grimsby, England. When someone handed her a white teddy bear she responded, "Thank you, I'll take that for my d--" before cutting herself off.

If the Duke and Duchess of Cambridge do have a girl, she could be the next queen of England thanks to the UK recently changing its laws of succession to remove any preference of gender. Previously, the firstborn male heir of the monarch would become king, and the firstborn daughter would only rule if she had no brothers, which is the case with Queen Elizabeth II. But with the change, if Kate and Will's firstborn is a girl, she will be in line to become the queen regnant, or the female monarch who rules in her own right. England follows in the footsteps of other European royals; Norway, Sweden, the Netherlands, and Belgium don't discriminate against firstborn royal daughters either. And there's also a chance Spain could have a queen regnant. Seven-year-old Infanta Leonor could rule if her parents don't have a son in the future.
