Duchess Kate turns 31 years old on January 9 and Prince William is planning to gift her with something huge. Royal insiders say that William has been house hunting.

He's "narrowed down the list to a few incredible places in Hampshire and Buckinghamshire around the £5 million mark."

William and Kate don't want their property "to be too close to London as they are already based in Buckingham palace. Wills has gathered together various property details from some high-end retail estates which he will give to her on her birthday."
