Is Kate Middleton ready for baby number four?

It seems like Kate Middleton has baby fever again, and we're not complaining!

While on a royal outing in Northern Island earlier this week, the Duchess of Cambridge mentioned to a royal fan that she was feeling "broody" after spotting a little baby in the crowd.

After spotting little James, Kate couldn't stop herself from going up to him and telling his dad Alan Barr: "He’s gorgeous. It makes me feel broody."

Kate then greeted James, saying: "You’re a very sweet little boy."

Alan then bolding asked the Duchess about her stance on a fourth child: "Baby number four?"

Laughing the question off, Kate replied: "I think William would be a little worried."

William and Kate left their three children in London for the two-day tour of Northern Ireland this week, but it was obvious that her children were on her mind when she spotted a little girl in a cute coat.

"I love your cool coat. Charlotte loves pink," she said.

William might not be a fan of the concept of a fourth child, but we certainly are!
