The Duchess of Cambridge has officially stepped out for the first time since announcing her third pregnancy!

The 35-year-old royal, who has not been seen since August 30, joined Prince William, 35, and Prince Harry, 33, to host an event at Buckingham Palace for mental health workers.

The duchess looked stunning in a powder blue Temperley London dress, which visibly showed a small bump.

Their Royal Highnesses invited guests from across the country who work in leading mental health organisations. #WorldMentalHealthDay was the perfect opportunity to celebrate their work.

The Duchess of Cambridge also met guests, many of whom have been working in the mental health sector for years. The reception recognises the progress of these organisations who are determined to raise awareness of mental health issues. #WorldMentalHealthDay

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, 4, and Princess Charlotte, 2.

An aide revealed tonight that the duchess is still suffering from hyperemesis gravidarum but said her condition is improving.
