People are convinced Kate Middleton is pregnant with her fourth child for THIS reason

Some committed royal fans are convinced that the Duchess of Cambridge, Kate Middleton, is soon to announce that she is pregnant with her fourth child.

• The Duchess of Cambridge has been giving away clues that she is pregnant, according to a body language expert.
• She recently changed her hairstyle, something she did before announcing she was pregnant with both Princess Charlotte and Prince George, and was even spotted cradling her stomach. 
• This follows royal news that Kate Middleton and Prince William are ‘delighted’ Prince George is making friends at school.

Of course, the Duchess has not revealed any news yet - and we don't even know whether she and Prince William want a fourth baby!

But according to a body language expert, and a number of fans, the mum-of-three has been dropping 'clues' that she is expecting another little royal.

The 37-year-old Duchess was recently pictured dropping four-year-old daughter, Princess Charlotte off for her first day of school, sporting a sleek and subtle new hairstyle - having added some blonde highlights to her brown locks.

The new do' triggered pregnancy rumours, due to the fact Kate changed her locks seven weeks before she announced she was pregnant with Prince George, and did the same shortly before Charlotte’s birth.

Commenting on the suspected clue, body language expert Judi James told the Daily Star: ‘Like a lot of women Kate does tend to change her hair when she is pregnant, although not dramatically.

‘The new style and colour she emerged with when she took George and Charlotte to school did look like one of her glossiest and most fashionable looks to date.

‘But then she did say she’d had it done for the school run, and it could have been aimed at giving her an emotional lift as Charlotte left home for school for the first time.’

Judi also pointed out how the future Queen consort was looking rather broody as she interacted with small children at a recent Royal Horticultural Society event and was even spotted holding her stomach.‘

These supposed tell tale signs have meant that popular bookmaker Ladbrokes have been forced to suspend customers from making bets on Kate having a baby in 2020.

They told The Sun: "Royal fans reckon Kate is showing early signs of a potential pregnancy.

"We're so confident the happy couple will add a fourth baby to their family we've now pulled the plug on all bets.

A smattering of royal fans have also had similar thoughts, with one writing on social media: 'Kate changed her hair again, I'm pretty sure she's pregnant AGAIN'.
