Life will never be the same for Kate

Kate Middleton faces a very different future ahead of her now she is to marry Prince William.

One day she will be a Princess, and possibly even Queen, at William's side - positions that will ensure her place in history.

But even before that her face will become famous world-wide.

Royal fans will treat her adoringly, while the newspapers will watch her every move.

And from one former palace aide comes a warning, Kate Middleton must find out quickly what her royal role is expected to be to prevent the same problems faced by Diana, Princess of Wales.

Patrick Jephson, who served as the Princess's private secretary, urged the new future Queen to turn her attention to the practical side of life within the Windsors.

"If they want her to be a wife, a pretty face, to keep quiet and stay in the background - get that straight now, not in the future," Mr Jephson said.

"If they want here to be more active and carry on the role Diana-style - let's get that straight too."

"If you speak to people who were around when Diana arrived, nobody had a serious talk to her about what she was going to do." Jephson continued.

"She made it up. She developed her own style and role and in the end it got out of synchronisation with the rest of the household."

He added: "Kate's not just going into a marriage, she's going into a business."
