Catherine, Duchess Of Cambridge has pulled out of another royal engagement as she continues to battle severe morning sickness.
The British royal is expecting her second child with husband Prince William, but has been struck down with hyperemesis gravidarum, the same condition which blighted her first pregnancy.
She axed a number of outings, including an official trip to Malta, but had hoped to return to work this week (beg29Sep14) by attending the launch of a charity project in London.
However, she has now confirmed she is not well enough to attend the event for The Art Room organisation.
The Duchess says in a statement, "I am truly sorry that I cannot be with you all... as you celebrate this milestone. As Patron of The Art Room I feel great pride to see the work that the charity is doing... I hope that you have a wonderful afternoon. My sincere apologies for not being able to join you but I hope that I will have an opportunity to visit... soon."
A spokesman for the royal insists she has no more engagements booked and future appointments will be "kept under review on a case by case basis".
The royal couple's first child, Prince George, was born last year (13).
