The Duchess of Cambridge could announce her fourth pregnancy "fairly soon," according to a royal expert.
The royal is already a mum to her three children with husband Prince William - Prince George, six, Princess Charlotte, four, and Prince Louis, one.
Now, Katharine Graves, author of The Hypnobirthing Book, has suggested the couple could announce another pregnancy soon after noticing a pattern.
Speaking to the Express, Katharine said: "The Duchess of Cambridge has timed her pregnancies with classic spaces.
"Two years between George and Charlotte and three years between Charlotte and Louis. On that basis, we could expect a fourth little Cambridge to be on the way fairly soon.
On that basis, we could expect a fourth little Cambridge to be on the way fairly soon.
"When you live in a goldfish bowl as the royal children do, it must be thoroughly healthy to have siblings to grow up with."
Meanwhile, the Duchess recently revealed Louis has started to talk.
Kate compared a little boy she met at Peterley Manor Farm in Buckinghamshire - where she was helping children pick out Christmas trees for their classrooms - to her youngest son after the youngster kept trying to get her attention by holding up his hand and said, "Me, me".
Speaking about 18-month-old Louis, the duchess stroked the boy's cheek and said: "You remind me of my little Louis, he keeps saying, 'Me, me, me.'
"And he wants to come everywhere with me!"
Farm owner Roger Brill told People magazine: "She was asking about the trees which drop their needles and those that don't, and which ones smell nice!
"She said that they normally have the Nordmann Fir inside that doesn't drop the needles."

The Duke and Duchess of Cambridge are very pleased to share some new photographs of their family as they visited the RHS Back to Nature Garden at the #ChelseaFlowerShow on Sunday afternoon. The photographs were taken by @mattporteous. The #RHSChelsea Back to Nature Garden, designed by The Duchess and award-winning landscape architects Andrée Davies and Adam White of Davies White Landscape Architects, is a woodland setting for families and communities to come together and connect with nature. Her Royal Highness is a strong advocate for the proven benefits the outdoors has on physical and mental health, and the positive impact that nature and the environment can have on childhood development in particular. Over the past months, Prince George, Princess Charlotte and Prince Louis have helped The Duchess gather moss, leaves and twigs to help decorate @The_RHS Back to Nature Garden. Hazel sticks collected by the family were also used to make the garden’s den. The Duchess told Monty Don in an interview for the BBC: “I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children. I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together.”
He added: "She was fantastic with the youngsters. She was in there moving them around and holding them up. I will have to give her a job at the weekend, I think. She was a very good saleswoman!"
