Room for one more?
According to royal expert Duncan Larcombe, Prince William and Kate Middleton may one day give Prince George, 7, Princess Charlotte, 6 and Prince Louis, 3, a little sibling.
"I don't think Kate and William have ever ruled out the possibility of baby number four," Larcombe told OK!. "Their children really bring out the best in them. Kate is a natural mother and very doting with children."
Though the pair — who just celebrated their 10th wedding anniversary on April 29 — will likely take on more duties now that Prince Philip passed away in April, the expert stated that motherhood will always be the Duchess of Cambridge's number one priority.
"With Kate, despite her focus on her royal duty, her family still come first," Larcombe noted. "I wouldn't be surprised if they decided on another baby."
The comments come on the heels of the couple's nostalgic trip to Scotland — where the pair first met and fell in love while attending the University of St Andrews.
"Their Royal Highnesses have been in the East Neuk of Fife today and surprised us by ending their visit with a takeaway fish supper, which the Duchess told us, was a lovely ‘trip down memory lane,'” Anstruther Fish Bar wrote on Facebook. "They enjoyed the whole takeaway experience, as most visitors to Anstruther do, sitting on a bench by the harbour, while no doubt keeping a watchful eye out for the local, hungry seagulls!"
"Before heading back to their waiting helicopter, they popped in for some ice cream and to chat with some of our thrilled staff," the message continued. "The Duke thanked us for the fish and chips and made a point on telling Andrew that they were just as good, if not better than he remembered from his student days."
