Kate Middleton leaves the hospital with Prince William
The fashion designer – who has four children, Brooklyn, 13, Romeo, 10, Cruz, seven, and 17-month-old Harper, with husband David – was thrilled when she heard Duchess Catherine was pregnant and wanted to let her know she was thinking of her when she was in hospital with acute morning sickness.

A source said: "Victoria sent flowers and a card to congratulate William and Kate.

"Victoria really understands morning sickness and has suffered terribly from it herself during all her pregnancies. Victoria actually lose weight in the first trimesters and couldn't keep her food down, so she really felt for Kate, as she knew a little of what she was going through."

Victoria – who, along with David, attended William and Catherine's wedding last April – is also keen to give the unborn future king or queen some clothes to wear as she is set to have her create her own children's clothing range.

The source added to heat magazine: "Victoria is actually looking into starting her own range of children's clothes and would love for William and Kate's child to be the first in line to wear them."
