She married royalty, but she isn't. People get this confused all the time. When Queen Elizabeth II married (i forgot his name) He became Dutch, and so has Catherine. Might i just say, I'd prefer her to be a lady then a commoner.
Catherine's title is Her Royal Highness, the Duchess of Cambridge. She is indeed a princess or they would not call her Her Royal Highness. Besides, before Prince Charles and Princess Diana were married, Diana was not a princess.
The queen's mother lived to be around a hundred, I believe. The queen could quite possibly outlive Prince Charles...if that happened...William would become King and Kate would become Queen. She is indeed a princess now...but their first formal title is Duke and Duchess of Cambridge. Many more titles will come assuming they both live long and healthy lives together.
I wonder if royals sign pre-nups? Or is a pre-nup more an American thing? I also wonder if the pressure is still there for a queen or potential queen to have a male heir?
She's married to the Prince.
I suppose that technically makes her a Princess now.
I keep wondering if, whenever William does become King, will that make her Queen or King's Consort?
Because although the British have a Queen, and she has a husband, he is NOT King.
