Did Kate Middleton just hint at royal baby No. 4?

Catherine, Duchess of Cambridge, has suggested that she may be keen for another baby but told royal watchers that “William would be worried”.

Kate Middleton admitted to “feeling a little broody” today after she met a royal fan’s baby during her and William’s tour of Northern Ireland.

The Sun reports that in between cooing over the little one, the Duchess joked that “William would be little worried” by the arrival of a fourth child.

Kate, who comes from a family of three children herself, laughed and said: “I think William would be a little worried.

She also commented on a little girl’s coat, saying: “I love your cool coat. Charlotte loves pink.”

Several hundred people lined the streets of the Co Antrim town as William and Kate went on a walkabout.

The crowds, many waving flags, braved the cold outside the Braid Centre.

The couple were there to learn more about the work of Cinemagic — a charity that uses film, TV and digital technologies to inspire and educate young people.

The visit to Ballymena comes after a range of high-energy engagements on Wednesday.

William and Kate played football at Belfast’s Windsor Park and took part in a canoe race in Co Fermanagh, before rounding the day off by pulling pints at a reception for young leaders at Belfast’s famous Empire music hall.
