Kate Middleton's grandaunt thinks her niece is too good for Prince William

Kate Middleton's relatives seem to be against her marrying Prince William, with her grandaunt even saying that she is too good for the royals.

Middleton, 29, will be tying the knot with William on April 29 at Westminster Abbey, but her family members have expressed their fears for the life she will have to lead as a royal.

"I think she's too good for them. I don't think she knows what she's letting herself in for," the Daily Star quoted Alice Goldsmith, the older sister of Kate's grandfather Ron, as saying.

Channel 4 bosses tracked down secret relatives of the future Queen of Britain in the documentary 'Meet The Middletons'.

"She has a very busy life ahead of her and I feel sorry for her really. They're a smashing couple and when you see them on TV they seem very natural and down-to-earth," John Harrison, 63, who is Kate's second cousin, said.

"But she's got such a busy life ahead of her with all of her tours and being told what to do," he stated.
