Kate Tells William "Make Me Your Queen Now!"

To the outside observer, Kate Middleton comes across as quiet, elegant and demure — everything the world would expect from the future Queen of England. But OK! has learned that when it comes to her romance with Prince William, she's the one calling the shots. And according to sources inside England's royal family, the 25-year-old beauty is pushing him to propose!

“I know William has said publicly that he doesn’t want to get married until he is 28 or 30, but he’s been going out with her a long time now,” a source close to the couple reveals to OK!. “It wouldn’t look good if he was seen to have strung her along and then it didn’t happen.”

On Oct. 5, the couple was spotted exiting London's Boujis nightclub, their first joint sighting since their April split. A week earlier, they reportedly enjoyed a romantic dinner at Italian eatery Locanda Ottoemezzo, where onlookers tell OK! the pair were holding hands. Both public outings fly in the face of orders from William's family, who want the relationship to mature away from the cameras.

As for when the young prince might cave to Kate's demands and propose, the source tells OK!, "I wouldn't hold your breath."
