Kate Middleton might be the "glue" between Prince William and King Charles when tensions get high, but that doesn't mean Charles is ready to talk to his daughter-in-law about her becoming queen when the time comes.

Kate Middleton, who is celebrating her 43rd birthday on Jan. 9, has proven herself to be the shiniest jewel of the British monarchy. The princess is married to Prince William, heir to the throne.

Kate Middleton are poised to be Queen of England sometime in the future, and apparently King Charles and Queen Camilla have zero interest in giving her advice on the matter.
