Kate added an extra layer in the form of her dusky blue Mulberry coat costing £1,735 and carried an elegant navy clutch bag
The Duchess of Cambridge admitted to feeling broody while on a walkabout in Northern Ireland today.
Kate, 37, who is already mother to George, Charlotte and Louis, cooed over five-month-old baby James Barr after spotting the baby in the crowd outside the Braid Arts Centre in Ballymena.
Speaking to his father Alan, Kate said: 'He's a very sweet little boy... He's so diddy. Makes me very broody.'
When Mr Barr asked if that meant she is planning baby number four, Kate cracked a wry smile and added: 'I think William might be slightly worried.'
The Duchess, who donned a £1,735 Mulberry coat and Jenny Packham dress for the occasion, has joined husband Prince William for a busy two days of engagements in the region.
