Kate Middleton may have just dropped a major hint regarding her fourth pregnancy. There are rumors that the Duchess of Cambridge is expecting another baby with Prince William.

Earlier this month, the mom of three stepped out in public to accompany Prince George and Princess Charlotte to Thomas’s Battersea. During the royal siblings’ first day of school, Kate was photographed in a floral Michael Kors dress.

It was also evident that Kate cut her hair a bit, and she also dyed it with a different color. Eagle-eyed royal watchers claimed that the Duke of Cambridge’s wife usually changes her hairstyle and hair color months before she announces her pregnancy.

According to Express, changing the royal’s hairstyle and hair color makes it possible for her to draw attention from her growing baby bump to her hair. This way, royal fans would talk about her hairstyle and not her pregnancy.

It is common for members of the royal family to only announce pregnancies after the female royals have reached the end of their first trimester. Kate also did the same thing during her pregnancies with Prince George, Princess Charlotte and Prince Louis.

“New hair cut — is Kate pregnant again?” one royal fan tweeted. “She always sports a new hairstyle when she’s pregnant,” the royal fan added.

Kate cut a fringe during her pregnancy to Prince George. And before she announced her pregnancy to Prince Louis, she also sported a much shorter haircut.

“Kate changed her hair again, I’m pretty sure she’s pregnant,” another royal fan wrote. “When Kate’s pregnant she changes up her hair so people look at her hair and not her stomach,” another person commented. “Is baby 4 coming?”

Rumors about Kate’s pregnancy have been ripe shortly after she returned from her maternity leave. Royal fans and experts were convinced that Kate and Prince William want to have more children.

Earlier this year, the doting mom reportedly said that she was feeling broody after meeting a 5-month-old baby during her royal outing. And just last week, Kate proved that she’s natural around kids when she chatted and played with them at the launch of her Back to Nature garden.
