After months of rumours that Prince William and Kate Middleton’s relationship was troubled because he was unkeen to commit, now Kate is reportedly having second thoughts about their future because she’s worried about one day being Queen.

A source close to the wannabe photographer told the News of the World recently: “She and Wills love each other dearly but Kate has just woken up to what the next few years could have in store.”

“She is suddenly realising the enormity of what could lie ahead if she walks down the aisle with William. It’s one thing having an on-off relationship with Wills, it’s quite another thing becoming Queen.”

“Kate is concerned that those before her who have married into the royal family have come from an aristocratic background and are from old money.”

“She has seen how the royal family washed their hands with Diana - and the princess had a privileged background and came from the right breeding.”

“Even Sarah Ferguson’s dad was an army man through and through and was part of the polo set. Kate is just from a very normal middle-class family who have done exceptionally well for themselves.”

“They don’t live on a huge estate or have titles before their names.”

The couple, who met at university four years ago, split up in April but secretly reunited again shortly afterwards. Prince William is second in line to the throne after his father, Prince Charles.
