12. Kate Middleton
Kate Middleton was not yet a royal when she turned 25 in 2007, but she was well on her way to becoming one.

Kate met Prince William in 2001, but did not begin dating until 2003. They had a brief breakup in 2007 (after her January birthday), but reconciled and became engaged in October 2010. As we all know, they are now married with three children, who we feel like will be 25 themselves before we even know it.
