The Duchess' baby bump

The Duchess of Cambridge revealed a tiny baby bump tonight as she made her first public appearance since announcing her pregnancy last month.

The 35-year-old royal, who has not been seen in public since August 30, joined Prince William, 35, and Price Harry, 33, to host a glittering Buckingham Palace reception to mark World Mental Health Day.

She looked radiant in a £795 powder blue lace dress by Temperley London which skimmed over her bump.

Kate has taken six weeks off royal duties after being struck down with the same severe strand of morning sickness that she suffered while pregnant with Prince George, four, and Princess Charlotte, two. It forced Kensington Palace to announce her pregnancy far earlier than planned.

An aide revealed tonight that the duchess is still suffering from hyperemesis gravidarum but said her condition is improving. She added Kate was determined to attend the event because the cause is close to her heart.

Guests praised the royal for attending despite her condition with Dr Nicola Byrom, of charity Student Minds, added: 'She's amazing. What a fighter that she's here.'

The palace is likely to confirm Kate’s due date soon, once she passes the 12-week date at which the risk of miscarriage is reduced. While she may appear at some events, there is no indication she is well enough to resume full royal duties. 

Tonight an aide said: 'The Duchess' condition is improving but she is still suffering from hyperemesis gravidarum. She is delighted to be able to be here tonight.'

Indeed Kate appeared to be in excellent spirits as she greeted guests alongside her husband and brother-in-law in one of the palace's opulent reception rooms.
