In true Kate style, she accessorised with a trusty pair of black suede court shoes and wore her hair in her trademark blow-dried style, looking more than comfortable in the stylish outfit as she danced with a human-size Paddington Bear - making Princes William and Harry giggle on the sidelines.
The Duchess of Cambridge made an unexpected visit to Paddington Station on Monday morning.
Kate Middleton joined actor Hugh Bonneville and other cast members from Paddington 2 to welcome 130 children from a dozen charities supported by the royal trio. It is in a dress pale pink belted it became evident that the mom-to-be, revealing the handsome forms of her baby bump emerging.
Kate was also joined by Prince Harry as they greeted the bear and had a little dance while briefly exchanging a few words.
Since Kensington Palace announced last month that Kate Middleton is pregnant with her third child with Prince William, she has retreated from the public eye-she suffers an extreme form of morning sickness called hyperemesis gravidarum-and even missed Prince George's first day of school.
The Duchess of Cambridge speaks to children from the charities she supports onboard the Belmond British Pullman train at Paddington Station.
But the mom-of-two, who's expecting her third child next spring, looked happy and healthy as she danced with the adorable bear on the train platform.
Her husband said the duchess was "feeling much better" while a royal aide said she is "better, but still suffering".
Paddington seemed to be in his element at his namesake train station, and was clearly quite the fan of calypso music; as soon as the band nearby struck up a tune, the loveable bear was tapping his feet.
